Merge branch 'for-4.3/blkcg' of git://git.kernel.dk/linux-block
Pull blk-cg updates from Jens Axboe: "A bit later in the cycle, but this has been in the block tree for a a while. This is basically four patchsets from Tejun, that improve our buffered cgroup writeback. It was dependent on the other cgroup changes, but they went in earlier in this cycle. Series 1 is set of 5 patches that has cgroup writeback updates: - bdi_writeback iteration fix which could lead to some wb's being skipped or repeated during e.g. sync under memory pressure. - Simplification of wb work wait mechanism. - Writeback tracepoints updated to report cgroup. Series 2 is is a set of updates for the CFQ cgroup writeback handling: cfq has always charged all async IOs to the root cgroup. It didn't have much choice as writeback didn't know about cgroups and there was no way to tell who to blame for a given writeback IO. writeback finally grew support for cgroups and now tags each writeback IO with the appropriate cgroup to charge it against. This patchset updates cfq so that it follows the blkcg each bio is tagged with. Async cfq_queues are now shared across cfq_group, which is per-cgroup, instead of per-request_queue cfq_data. This makes all IOs follow the weight based IO resource distribution implemented by cfq. - Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff. - Other misc review points addressed, acks added and rebased. Series 3 is the blkcg policy cleanup patches: This patchset contains assorted cleanups for blkcg_policy methods and blk[c]g_policy_data handling. - alloc/free added for blkg_policy_data. exit dropped. - alloc/free added for blkcg_policy_data. - blk-throttle's async percpu allocation is replaced with direct allocation. - all methods now take blk[c]g_policy_data instead of blkcg_gq or blkcg. And finally, series 4 is a set of patches cleaning up the blkcg stats handling: blkcg's stats have always been somwhat of a mess. This patchset tries to improve the situation a bit. - The following patches added to consolidate blkcg entry point and blkg creation. This is in itself is an improvement and helps colllecting common stats on bio issue. - per-blkg stats now accounted on bio issue rather than request completion so that bio based and request based drivers can behave the same way. The issue was spotted by Vivek. - cfq-iosched implements custom recursive stats and blk-throttle implements custom per-cpu stats. This patchset make blkcg core support both by default. - cfq-iosched and blk-throttle keep track of the same stats multiple times. Unify them" * 'for-4.3/blkcg' of git://git.kernel.dk/linux-block: (45 commits) blkcg: use CGROUP_WEIGHT_* scale for io.weight on the unified hierarchy blkcg: s/CFQ_WEIGHT_*/CFQ_WEIGHT_LEGACY_*/ blkcg: implement interface for the unified hierarchy blkcg: misc preparations for unified hierarchy interface blkcg: separate out tg_conf_updated() from tg_set_conf() blkcg: move body parsing from blkg_conf_prep() to its callers blkcg: mark existing cftypes as legacy blkcg: rename subsystem name from blkio to io blkcg: refine error codes returned during blkcg configuration blkcg: remove unnecessary NULL checks from __cfqg_set_weight_device() blkcg: reduce stack usage of blkg_rwstat_recursive_sum() blkcg: remove cfqg_stats->sectors blkcg: move io_service_bytes and io_serviced stats into blkcg_gq blkcg: make blkg_[rw]stat_recursive_sum() to be able to index into blkcg_gq blkcg: make blkcg_[rw]stat per-cpu blkcg: add blkg_[rw]stat->aux_cnt and replace cfq_group->dead_stats with it blkcg: consolidate blkg creation in blkcg_bio_issue_check() blk-throttle: improve queue bypass handling blkcg: move root blkg lookup optimization from throtl_lookup_tg() to __blkg_lookup() blkcg: inline [__]blkg_lookup() ... |

x86, mm: trace when an IPI is about to be sent
When unmapping pages it is necessary to flush the TLB. If that page was accessed by another CPU then an IPI is used to flush the remote CPU. That is a lot of IPIs if kswapd is scanning and unmapping >100K pages per second. There already is a window between when a page is unmapped and when it is TLB flushed. This series increases the window so multiple pages can be flushed using a single IPI. This should be safe or the kernel is hosed already. Patch 1 simply made the rest of the series easier to write as ftrace could identify all the senders of TLB flush IPIS. Patch 2 tracks what CPUs potentially map a PFN and then sends an IPI to flush the entire TLB. Patch 3 tracks when there potentially are writable TLB entries that need to be batched differently Patch 4 increases SWAP_CLUSTER_MAX to further batch flushes The performance impact is documented in the changelogs but in the optimistic case on a 4-socket machine the full series reduces interrupts from 900K interrupts/second to 60K interrupts/second. This patch (of 4): It is easy to trace when an IPI is received to flush a TLB but harder to detect what event sent it. This patch makes it easy to identify the source of IPIs being transmitted for TLB flushes on x86.

sound updates for 4.3-rc1
There are little changes in core part, but lots of development are found in drivers, especially ASoC. The diffstat shows regmap- related changes for a slight API additions / changes, and that's all. Looking at the code size statistics, the most significant addition is for Intel Skylake. (Note that SKL support is still underway, the codec driver is missing.) Also STI controller driver is a major addition as well as a few new codec drivers. In HD-audio side, there are fewer changes than the past. The noticeable change is the support of ELD notification from i915 graphics driver. Thus this pull request carries a few changes in drm/i915. Other than that, USB-audio got a rewrite of runtime PM code. It was initiated by lockdep warning, but resulted in a good cleanup in the end. Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJV6TwJAAoJEGwxgFQ9KSmkZoEP/06GrsGlfgIfBbnlAKcsZ0t0 RDDCbxmwD8IsjTk180Gs3qBuhVPurhmPxq6Leow5fBktkEK5bIN3eAQkO9aIMroW xxU1UF6Q9XE2j97e/PhhUld7/NP0IQK/YTMuwX74G2kfEkA9Lktl4UjNMw9mKJX2 8OIwz8ZuqSG60znmGlgiqRE4M3Svs1L/jVP1wrPg2DXQfe+ptAJpUTsyVGOMRWm3 IaJ9h5OelPg8Jm61zcg6/pgsdYx4oquCV5wLwMz8rzIUfHb7ox8F7YKOzB+sXtYI zcsTfF2CqifoBcQAh9c+XE4+gMamAdheA+uc8ScUkcskucTj4Fr5tXLiPSN9QMt4 QGOOVjqcpWv5rWwAgzUJvl1/PT4HyQfkXn5tEQVGdg9Ab1SIcQBzD1+nHUV94vKZ N7/grMdqJ56zUGK2fEcBS6BEDlaSToOIHDrQ1iPFNBvmW8qjBq9tYaufTGC6Vtj2 0YKJukzIbyqLIgQtQf44aqLouFIz2lq437PqRQ4W+9C3FwGN9FKCYJ/JzvOGDIJa sSjEwQkJ9vnmZ3E2B30NKb24TG8pPq9WPIN2Rqe5EbHctU3gEnMScwvmG7SmCSG5 LtDVr6Q5XKFM56cVb7tdZl6Jv97BvGu6EERM+zN+8YyMver206rC8upWOev6R2q3 asvLDEchv7Qm3upx+PYg =/sXs -----END PGP SIGNATURE----- Merge tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There are little changes in core part, but lots of development are found in drivers, especially ASoC.

Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier" * tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) drm/i915: Add locks around audio component bind/unbind drm/i915: Drop port_mst_index parameter from pin/eld callback ALSA: hda - Fix missing inline for dummy snd_hdac_set_codec_wakeup() ALSA: hda - Wake the codec up on pin/ELD notify events ALSA: hda - allow codecs to access the i915 pin/ELD callback drm/i915: Call audio pin/ELD notify function drm/i915: Add audio pin sense / ELD callback ASoC: zx296702-i2s: Fix resource leak when unload module ASoC: sti_uniperif: Ensure component is unregistered when unload module ASoC: au1x: psc-i2s: Convert to use devm_ioremap_resource ASoC: sh: dma-sh7760: Convert to devm_snd_soc_register_platform ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leak ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc failure ASoC: Clean up docbook warnings ASoC: txx9: Convert to devm_snd_soc_register_platform ASoC: pxa: Convert to devm_snd_soc_register_platform ASoC: nuc900: Convert to devm_snd_soc_register_platform ASoC: blackfin: Convert to devm_snd_soc_register_platform ASoC: au1x: Convert to devm_snd_soc_register_platform ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops ... |

net: sunrpc: fix tracepoint Warning: unknown op '->'
`perf stat -e sunrpc:svc_xprt_do_enqueue true` results in
Warning: unknown op '->'
Warning: [sunrpc:svc_xprt_do_enqueue] unknown op '->'
Similar warning for svc_handle_xprt as well.
Actually TP_printk() should never dereference an address saved in the ring
buffer that points somewhere in the kernel. There's no guarantee that that
object still exists (with the exception of static strings).
Therefore change all the arguments for TP_printk(), so that it references
values existing in the ring buffer only.
While doing that, also fix another possible bug when argument xprt could be
NULL and TP_fast_assign() tries to access it's elements.

spmi: add command tracepoints for SPMI
Add tracepoints to retrieve information about read, write and non-data commands. For performance measurement support tracepoints are added at the beginning and at the end of transfers. Following is a list showing the new tracepoint events. The "cmd" parameter here represents the opcode, SID, and full 16-bit address. spmi_write_begin: cmd and data buffer. spmi_write_end : cmd and return value. spmi_read_begin : cmd. spmi_read_end : cmd, return value and data buffer. spmi_cmd : cmd. The reason that cmd appears at both the beginning and at the end event is that SPMI drivers can request commands concurrently. cmd helps in matching the corresponding events. SPMI tracepoints can be enabled like: echo 1 >/sys/kernel/debug/tracing/events/spmi/enable and will dump messages that can be viewed in /sys/kernel/debug/tracing/trace that look like: ... spmi_read_begin: opc=56 sid=00 addr=0x0000 ... spmi_read_end: opc=56 sid=00 addr=0x0000 ret=0 len=02 buf=0x[01-40] ... spmi_write_begin: opc=48 sid=00 addr=0x0000 len=3 buf=0x[ff-ff-ff] Suggested-by: Sagar Dharia <sdharia@codeaurora.org> Acked-by: Steven Rostedt <rostedt@goodmis.org> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Gilad Avidov <gavidov@codeaurora.org> Signed-off-by: Ankit Gupta <ankgupta@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

thermal: consistently use int for temperatures
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

The functionality of ext3 is fully supported by ext4 driver. Major distributions (SUSE, RedHat) already use ext4 driver to handle ext3 filesystems for quite some time. There is some ugliness in mm resulting from jbd cleaning buffers in a dirty page without cleaning page dirty bit and also support for buffer bouncing in the block layer when stable pages are required is there only because of jbd. So let's remove the ext3 driver. This saves us some 28k lines of duplicated code. Acked-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jan Kara <jack@suse.cz> |

This patch series contains several clean ups and even a new trace clock
"monitonic raw". Also some enhancements to make the ring buffer even faster. But the biggest and most noticeable change is the renaming of the ftrace* files, structures and variables that have to deal with trace events. Over the years I've had several developers tell me about their confusion with what ftrace is compared to events. Technically, "ftrace" is the infrastructure to do the function hooks, which include tracing and also helps with live kernel patching. But the trace events are a separate entity altogether, and the files that affect the trace events should not be named "ftrace". These include: include/trace/ftrace.h -> include/trace/trace_events.h include/linux/ftrace_event.h -> include/linux/trace_events.h Also, functions that are specific for trace events have also been renamed: ftrace_print_*() -> trace_print_*() (un)register_ftrace_event() -> (un)register_trace_event() ftrace_event_name() -> trace_event_name() ftrace_trigger_soft_disabled()-> trace_trigger_soft_disabled() ftrace_define_fields_##call() -> trace_define_fields_##call() ftrace_get_offsets_##call() -> trace_get_offsets_##call() Structures have been renamed: ftrace_event_file -> trace_event_file ftrace_event_{call,class} -> trace_event_{call,class} ftrace_event_buffer -> trace_event_buffer ftrace_subsystem_dir -> trace_subsystem_dir ftrace_event_raw_##call -> trace_event_raw_##call ftrace_event_data_offset_##call-> trace_event_data_offset_##call ftrace_event_type_funcs_##call -> trace_event_type_funcs_##call And a few various variables and flags have also been updated. This has been sitting in linux-next for some time, and I have not heard a single complaint about this rename breaking anything. Mostly because these functions, variables and structures are mostly internal to the tracing system and are seldom (if ever) used by anything external to that. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJViYhVAAoJEEjnJuOKh9ldcJ0IAI+mytwoMAN/CWDE8pXrTrgs aHlcr1zorSzZ0Lq6lKsWP+V0VGVhP8KWO16vl35HaM5ZB9U+cDzWiGobI8JTHi/3 eeTAPTjQdgrr/L+ZO1ApzS1jYPhN3Xi5L7xublcYMJjKfzU+bcYXg/x8gRt0QbG3 S9QN/kBt0JIIjT7McN64m5JVk2OiU36LxXxwHgCqJvVCPHUrriAdIX7Z5KRpEv13 zxgCN4d7Jiec/FsMW8dkO0vRlVAvudZWLL7oDmdsvNhnLy8nE79UOeHos2c1qifQ LV4DeQ+2Hlu7w9wxixHuoOgNXDUEiQPJXzPc/CuCahiTL9N/urQSGQDoOVMltR4= =hkdz -----END PGP SIGNATURE----- Merge tag 'trace-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This patch series contains several clean ups and even a new trace clock "monitonic raw".

These include: include/trace/ftrace.h -> include/trace/trace_events.h include/linux/ftrace_event.h -> include/linux/trace_events.h Also, functions that are specific for trace events have also been renamed: ftrace_print_*() -> trace_print_*() (un)register_ftrace_event() -> (un)register_trace_event() ftrace_event_name() -> trace_event_name() ftrace_trigger_soft_disabled() -> trace_trigger_soft_disabled() ftrace_define_fields_##call() -> trace_define_fields_##call() ftrace_get_offsets_##call() -> trace_get_offsets_##call() Structures have been renamed: ftrace_event_file -> trace_event_file ftrace_event_{call,class} -> trace_event_{call,class} ftrace_event_buffer -> trace_event_buffer ftrace_subsystem_dir -> trace_subsystem_dir ftrace_event_raw_##call -> trace_event_raw_##call ftrace_event_data_offset_##call-> trace_event_data_offset_##call ftrace_event_type_funcs_##call -> trace_event_type_funcs_##call And a few various variables and flags have also been updated. This has been sitting in linux-next for some time, and I have not heard a single complaint about this rename breaking anything. Mostly because these functions, variables and structures are mostly internal to the tracing system and are seldom (if ever) used by anything external to that" * tag 'trace-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (33 commits) ring_buffer: Allow to exit the ring buffer benchmark immediately ring-buffer-benchmark: Fix the wrong type ring-buffer-benchmark: Fix the wrong param in module_param ring-buffer: Add enum names for the context levels ring-buffer: Remove useless unused tracing_off_permanent() ring-buffer: Give NMIs a chance to lock the reader_lock ring-buffer: Add trace_recursive checks to ring_buffer_write() ring-buffer: Allways do the trace_recursive checks ring-buffer: Move recursive check to per_cpu descriptor ring-buffer: Add unlikelys to make fast path the default tracing: Rename ftrace_get_offsets_##call() to trace_event_get_offsets_##call() tracing: Rename ftrace_define_fields_##call() to trace_event_define_fields_##call() tracing: Rename ftrace_event_type_funcs_##call to trace_event_type_funcs_##call tracing: Rename ftrace_data_offset_##call to trace_event_data_offset_##call tracing: Rename ftrace_raw_##call event structures to trace_event_raw_##call tracing: Rename ftrace_trigger_soft_disabled() to trace_trigger_soft_disabled() tracing: Rename FTRACE_EVENT_FL_* flags to EVENT_FILE_FL_* tracing: Rename struct ftrace_subsystem_dir to trace_subsystem_dir tracing: Rename ftrace_event_name() to trace_event_name() tracing: Rename FTRACE_MAX_EVENT to TRACE_EVENT_TYPE_MAX ... |

The cpufreq core fixes from Viresh Kumar are quite significant too as far as the number of commits goes and because they should reduce CPU online/offline overhead quite a bit in the majority of cases. From the new featues point of view, the ACPICA update (to upstream revision 20150515) adding support for new ACPI 6 material to ACPICA is the one that matters the most as some new significant features will be based on it going forward. Also included is an update of the ACPI device power management core to follow ACPI 6 (which in turn reflects the Windows' device PM implementation), a PM core extension to support wakeup interrupts in a more generic way and support for the ACPI _CCA device configuration object. The rest is mostly fixes and cleanups all over and some documentation updates, including new DT bindings for Operating Performance Points. There is one fix for a regression introduced in the 4.1 cycle, but it adds quite a number of lines of code, it wasn't really ready before Thursday and you were on vacation, so I refrained from pushing it on the last minute for 4.1.

ext4: minor cleanup of ext4_da_reserve_space()
Remove outdated comments and dead code from ext4_da_reserve_space. Clean up its trace point, and relocate it to make it more useful. While we're at it, fix a nearby conditional used to determine if we have a non-bigalloc file system. It doesn't match usage elsewhere in the code, and misleadingly suggests that an s_cluster_ratio value of 0 would be legal.

timer: Replace timer base by a cpu index
Instead of storing a pointer to the per cpu tvec_base we can simply cache a CPU index in the timer_list and use that to get hold of the correct per cpu tvec_base. This is only used in lock_timer_base() and the slightly larger code is peanuts versus the spinlock operation and the d-cache foot print of the timer wheel. Aside of that this allows to get rid of following nuisances: - boot_tvec_base That statically allocated 4k bss data is just kept around so the timer has a home when it gets statically initialized. It serves no other purpose. With the CPU index we assign the timer to CPU0 at static initialization time and therefor can avoid the whole boot_tvec_base dance. That also simplifies the init code, which just can use the per cpu base. Before: text data bss dec hex filename 17491 9201 4160 30852 7884 ../build/kernel/time/timer.o After: text data bss dec hex filename 17440 9193 0 26633 6809 ../build/kernel/time/timer.o - Overloading the base pointer with various flags The CPU index has enough space to hold the flags (deferrable, irqsafe) so we can get rid of the extra masking and bit fiddling with the base pointer. As a benefit we reduce the size of struct timer_list on 64 bit machines. 4 - 8 bytes, a size reduction up to 15% per struct timer_list, which is a real win as we have tons of them embedded in other structs. This changes also the newly added deferrable printout of the timer start trace point to capture and print all timer->flags, which allows us to decode the target cpu of the timer as well. We might have used bitfields for this, but that would change the static initializers and the init function for no value to accomodate big endian bitfields.

ext4: Add support FALLOC_FL_INSERT_RANGE for fallocate
This patch implements fallocate's FALLOC_FL_INSERT_RANGE for Ext4. 1) Make sure that both offset and len are block size aligned. 2) Update the i_size of inode by len bytes. 3) Compute the file's logical block number against offset. If the computed block number is not the starting block of the extent, split the extent such that the block number is the starting block of the extent. 4) Shift all the extents which are lying between [offset, last allocated extent] towards right by len bytes. This step will make a hole of len bytes at offset. Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com> Signed-off-by: Ashish Sangwan <a.sangwan@samsung.com> |

target: Minimize SCSI header #include directives
Only include SCSI initiator header files in target code that needs these header files, namely the SCSI pass-through code and the tcm_loop driver. Change SCSI_SENSE_BUFFERSIZE into TRANSPORT_SENSE_BUFFER in target code because the former is intended for initiator code and the latter for target code. With this patch the only initiator include directives in target code that remain are as follows: $ git grep -nHE 'include .scsi/(scsi.h|scsi_host.h|scsi_device.h|scsi_cmnd.h)' drivers/target drivers/infiniband/ulp/{isert,srpt} drivers/usb/gadget/legacy/tcm_*.[ch] drivers/{vhost,xen} include/{target,trace/events/target.h} drivers/target/loopback/tcm_loop.c:29:#include <scsi/scsi.h> drivers/target/loopback/tcm_loop.c:31:#include <scsi/scsi_host.h> drivers/target/loopback/tcm_loop.c:32:#include <scsi/scsi_device.h> drivers/target/loopback/tcm_loop.c:33:#include <scsi/scsi_cmnd.h> drivers/target/target_core_pscsi.c:39:#include <scsi/scsi_device.h> drivers/target/target_core_pscsi.c:40:#include <scsi/scsi_host.h> drivers/xen/xen-scsiback.c:52:#include <scsi/scsi_host.h> /* SG_ALL */ Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com> |

writeback: move global_dirty_limit into wb_domain
This patch is a part of the series to define wb_domain which represents a domain that wb's (bdi_writeback's) belong to and are measured against each other in. This will enable IO backpressure propagation for cgroup writeback. global_dirty_limit exists to regulate the global dirty threshold which is a property of the wb_domain. This patch moves hard_dirty_limit, dirty_lock, and update_time into wb_domain. This is pure reorganization and doesn't introduce any behavioral changes.
