By using lockdep_assert_*() from seqlock.h, the spaghetti monster
attacked.
Attack back by reducing seqlock.h dependencies from two key high level headers:
- <linux/seqlock.h>: -Remove <linux/ww_mutex.h>
- <linux/time.h>: -Remove <linux/seqlock.h>
- <linux/sched.h>: +Add <linux/seqlock.h>
The price was to add it to sched.h ...
Core header fallout, we add direct header dependencies instead of gaining them
parasitically from higher level headers:
- <linux/dynamic_queue_limits.h>: +Add <asm/bug.h>
- <linux/hrtimer.h>: +Add <linux/seqlock.h>
- <linux/ktime.h>: +Add <asm/bug.h>
- <linux/lockdep.h>: +Add <linux/smp.h>
- <linux/sched.h>: +Add <linux/seqlock.h>
- <linux/videodev2.h>: +Add <linux/kernel.h>
Arch headers fallout:
- PARISC: <asm/timex.h>: +Add <asm/special_insns.h>
- SH: <asm/io.h>: +Add <asm/page.h>
- SPARC: <asm/timer_64.h>: +Add <uapi/asm/asi.h>
- SPARC: <asm/vvar.h>: +Add <asm/processor.h>, <asm/barrier.h>
-Remove <linux/seqlock.h>
- X86: <asm/fixmap.h>: +Add <asm/pgtable_types.h>
-Remove <asm/acpi.h>
There's also a bunch of parasitic header dependency fallout in .c files, not listed
separately.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
