Set the new flag in flagged_taskfile() and move the code modifying

While at it remove the bogus comment: ->tf_in_flags (except .b.data)

Currently it's possible to ide-cd to set an incorrect blocksize by
reading garbage if the drive is dead:
ide_cd_probe()
-> cdrom_read_toc()
-> cdrom_read_capacity()
-> cdrom_queue_packet_command()
-> ide_do_drive_cmd()
-> ide_do_request()
-> start_request()
on start_request():
/* bail early if we've exceeded max_failures */
if (drive->max_failures && (drive->failures > drive->max_failures)) {
goto kill_rq;
}
(...)
kill_rq:
ide_kill_rq(drive, rq);
return ide_stopped;
ide_kill_rq() and the next calls won't set REQ_FAILED on rq->cmd_flags and thus
cdrom_queue_packet_command() won't return an error. then:
stat = cdrom_queue_packet_command(drive, &req);
if (stat == 0) {
*capacity = 1 + be32_to_cpu(capbuf.lba);
*sectors_per_frame =
be32_to_cpu(capbuf.blocklen) >> SECTOR_BITS;
}
cdrom_read_capacity() ends believing capbuf is valid but in fact it's just
uninitialized data. back to cdrom_read_toc():
/* Try to get the total cdrom capacity and sector size. */
stat = cdrom_read_capacity(drive, &toc->capacity, §ors_per_frame,
sense);
if (stat)
toc->capacity = 0x1fffff;
set_capacity(info->disk, toc->capacity * sectors_per_frame);
/* Save a private copy of te TOC capacity for error handling */
drive->probed_capacity = toc->capacity * sectors_per_frame;
blk_queue_hardsect_size(drive->queue,
sectors_per_frame << SECTOR_BITS);
that will set drive->queue->hardsect_size to be the random value.
hardsect_size is used to calculate inode->i_blkbits. later on, on a read
path:
void create_empty_buffers(struct page *page,
unsigned long blocksize, unsigned long b_state)
{
struct buffer_head *bh, *head, *tail;
head = alloc_page_buffers(page, blocksize, 1);
bh = head;
do {
bh->b_state |= b_state;
tail = bh;
bh = bh->b_this_page;
} while (bh);
tail->b_this_page = head;
alloc_page_buffers() will return NULL if blocksize > 4096. blocksize is
calculed based on inode->i_blkbits. that will trigger a null
dereference on create_empty_buffers().

This can be broken down into these major areas:
- Documentation updates (language translations and fixes, as
well as kobject and kset documenatation updates.)
- major kset/kobject/ktype rework and fixes. This cleans up the
kset and kobject and ktype relationship and architecture,
making sense of things now, and good documenation and samples
are provided for others to use. Also the attributes for
kobjects are much easier to handle now. This cleaned up a LOT
of code all through the kernel, making kobjects easier to use
if you want to.
- struct bus_type has been reworked to now handle the lifetime
rules properly, as the kobject is properly dynamic.
- struct driver has also been reworked, and now the lifetime
issues are resolved.
- the block subsystem has been converted to use struct device
now, and not "raw" kobjects. This patch has been in the -mm
tree for over a year now, and finally all the issues are
worked out with it. Older distros now properly work with new
kernels, and no userspace updates are needed at all.
- nozomi driver is added. This has also been in -mm for a long
time, and many people have asked for it to go in. It is now
in good enough shape to do so.
- lots of class_device conversions to use struct device instead.
The tree is almost all cleaned up now, only SCSI and IB is the
remaining code to fix up...
