60b8cabd8e Driver Core: fix bug in device_rename() for SYSFS_DEPRECATED=y
This should fix the sysfs warnings that renaming network devices is
causing to show up with CONFIG_SYSFS_DEPRECATED=y

The code just shouldn't run if class devices are real directories, it's
an update for the symlink in the class directory. Nobody noticed that as
long as the creation of sysfs files silently failed, and we both missed
it before the merge, because we don't run SYSFS_DEPRECATED=y.

bdb76ef5a4 dio: fix cache invalidation after sync writes
Commit commit 65b8291c40 ("dio: invalidate
clean pages before dio write") introduced a bug which stopped dio from
ever invalidating the page cache after writes.  It still invalidated it
before writes so most users were fine.

Karl Schendel reported ( http://lkml.org/lkml/2007/10/26/481 ) hitting
this bug when he had a buffered reader immediately reading file data
after an O_DIRECT wirter had written the data.  The kernel issued
read-ahead beyond the position of the reader which overlapped with the
O_DIRECT writer.  The failure to invalidate after writes caused the
reader to see stale data from the read-ahead.

The following patch is originally from Karl.  The following commentary
is his:

	The below 3rd try takes on your suggestion of just invalidating
	no matter what the retval from the direct_IO call.  I ran it
	thru the test-case several times and it has worked every time.
	The post-invalidate is probably still too early for async-directio,
	but I don't have a testcase for that;  just sync.  And, this
	won't be any worse in the async case.

I added a test to the aio-dio-regress repository which mimics Karl's IO
pattern.  It verifed the bad behaviour and that the patch fixed it.  I
agree with Karl, this still doesn't help the case where a buffered
reader follows an AIO O_DIRECT writer.  That will require a bit more
work.

This gives up on the idea of returning EIO to indicate to userspace that
stale data remains if the invalidation failed.

97855b49b6 locks: fix possible infinite loop in posix deadlock detection
It's currently possible to send posix_locks_deadlock() into an infinite
loop (under the BKL).

For now, fix this just by bailing out after a few iterations.  We may
want to fix this in a way that better clarifies the semantics of
deadlock detection.  But that will take more time, and this minimal fix
is probably adequate for any realistic scenario, and is simple enough to
be appropriate for applying to stable kernels now.

Thanks to George Davis for reporting the problem.

  I wonder on what type of UFS do you test this patch?  NetBSD and FreeBSD
  do not use "fs_state", they use "fs_clean" flag, only Solaris does check

  That's why parentheses was like that.

  At now with linux-2.6.24-rc1-git1, I get: fs need fsck, but NetBSD's fsck
  says that's all ok.

487e9bf25c fix tmpfs BUG and AOP_WRITEPAGE_ACTIVATE
It's possible to provoke unionfs (not yet in mainline, though in mm and
some distros) to hit shmem_writepage's BUG_ON(page_mapped(page)).  I expect
it's possible to provoke the 2.6.23 ecryptfs in the same way (but the
2.6.24 ecryptfs no longer calls lower level's ->writepage).

This came to light with the recent find that AOP_WRITEPAGE_ACTIVATE could
leak from tmpfs via write_cache_pages and unionfs to userspace.  There's
already a fix (e423003028 - writeback: don't
propagate AOP_WRITEPAGE_ACTIVATE) in the tree for that, and it's okay so
far as it goes; but insufficient because it doesn't address the underlying
issue, that shmem_writepage expects to be called only by vmscan (relying on
backing_dev_info capabilities to prevent the normal writeback path from
ever approaching it).

That's an increasingly fragile assumption, and ramdisk_writepage (the other
source of AOP_WRITEPAGE_ACTIVATEs) is already careful to check
wbc->for_reclaim before returning it.  Make the same check in
shmem_writepage, thereby sidestepping the page_mapped BUG also.

8bca44bbd3 mm/sparse-vmemmap.c: make sure init_mm is included
mm/sparse-vmemmap.c uses init_mm in some places.  However, it is not
present in any of the headers currently included in the file.

init_mm is defined as extern in sched.h, so we add it to the headers list

Up to now, this problem was masked by the fact that functions like
set_pte_at() and pmd_populate_kernel() are usually macros that expand to
simpler variants that does not use the first parameter at all.

cc72233c83 radeonfb: remove warning with CONFIG_PM=n
Remove warning from powerpc ppc64_defconfig builds:

drivers/video/aty/radeon_pm.c:30: warning: 'radeon_reinitialize_M10' declared 'static' but never defined

It's used only under CONFIG_PM, and only with CONFIG_X86 before it is
defined, so the forward declaration can be moved under the ifdef.

e027bd36c1 libata: implement and use ATA_QCFLAG_QUIET
Implement ATA_QCFLAG_QUIET which indicates that there's no need to
report if the command fails with AC_ERR_DEV and set it for passthrough
commands.

Combined with previous changes, this now makes device errors for all
direct commands reported directly to the issuer without going through
EH actions and reporting.

Note that EH is still invoked after non-IO device errors to determine
the nature of the error and resume command execution (some controller
requires special care after error to continue).  It just performs
default maintenance after error, examines what's going on, realizes
that it's none of its business and reports the command failure without
logging any error messages.

f90f0828e5 libata: stop being overjealous about non-IO commands
libata EH always revalidated device and retried failed command after
error except for ATAPI CCs.  This is unnecessary and hinders with
users issuing direct commands.  This patch makes the following
changes.

* Make sata_sil24 not request ATA_EH_REVALIDATE on device errors.
  sil24 is the only driver which does this.  All others let libata EH
  core code decide.

* Don't request revalidation after device error of non-IO command.
  Revalidation doesn't really help anybody.  As ATA_EH_REVALIDATE
  isn't set by default, there's no reason to clear it after sense data
  is read.  Kill ATA_EH_REVALIDATE clearing code while at it.

* Don't retry non-IO command after device error.  Device has rejected
  the command.  There's no point in retrying.

ATA_QCFLAG_IO is used to mark commands which are used to perform
regluar IO transfers via block layer.  These commands are assumed to
be valid and taken more seriously during error handling.  Cache flush
is used by regular IO path and necessary for data integrity.  Mark it
with ATA_QCFLAG_IO.
