 b) no need to bother with the stuff pointed to by iomem pointers,

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6:
  [PATCH] mnt_expire is protected by namespace_sem, no need for vfsmount_lock
  [PATCH] do shrink_submounts() for all fs types
  [PATCH] sanitize locking in mark_mounts_for_expiry() and shrink_submounts()
  [PATCH] count ghost references to vfsmounts
  [PATCH] reduce stack footprint in namespace.c

The Coverity checker spotted that we leak the storage allocated to 'name' in
int driver_add_kobj().  The leak looks legit to me - this is the code :

int driver_add_kobj(struct device_driver *drv, struct kobject *kobj,
                    const char *fmt, ...)
{
        va_list args;
        char *name;
        int ret;

        va_start(args, fmt);
        name = kvasprintf(GFP_KERNEL, fmt, args);
        ^^^^^^^^ This dynamically allocates space...

        va_end(args);

        if (!name)
                return -ENOMEM;

        return kobject_add(kobj, &drv->p->kobj, "%s", name);
	^^^^^^^^ This neglects to free the space allocated
}

Inside kobject_add() a copy of 'name' will be made and used.  As far as I can
see, Coverity is correct in flagging this as a leak, but I'd like some
configmation before the patch is applied.

This should fix it.

This patch also removes unnecessary "if (info)" checks:
suspend/resume/shutdown ops are executed only if probe() is succeeded, so info

Fix regression in dm-crypt introduced in commit
3a7f6c99 ("dm crypt: use async crypto").

If write requests need to be split into pieces, the code must not process them
in parallel because the crypto context cannot be shared.  So there can be
parallel crypto operations on one part of the write, but only one write bio
can be processed at a time.

This is not optimal and the workqueue code needs to be optimized for parallel
processing, but for now it solves the problem without affecting the
performance of synchronous crypto operation (most of current dm-crypt users).

This reverts commit 3c0a654e and
fixes kernel bug #10245:

	http://bugzilla.kernel.org/show_bug.cgi?id=10245

The HP Compaq nc6120 has the same PCI sub-device ID as the nx6110, and the
SMBus is used by ACPI for thermal management on the nc6120, so Linux should
not attach a native driver to it.  This means that this quirk is unsafe and
has to be removed.

I also added a comment to help developers realize that adding new IDs to this
SMBus unhiding quirk table should be done only with great care, and in
particular only after checking that ACPI is not making use of the SMBus.

The following patch allows ixp4xx-beeper to be loaded by udev
automatically when compiled as a module with kernel versions 2.4.24 and
greater.

This patch is required because 43cc71ee
("platform: prefix MODALIAS with "platform:"") changed the modalias
string to have the extra prefix.

LKG7102D7:~# udevinfo -a -p /sys/devices/platform/ixp4xx-beeper.4

 looking at device '/devices/platform/ixp4xx-beeper.4':
   KERNEL=="ixp4xx-beeper.4"
   SUBSYSTEM=="platform"
   DRIVER==""
   ATTR{modalias}=="platform:ixp4xx-beeper"

udev therefore tries to modprobe platform:ixp4xx-beeper instead of
ixp4xx-beeper.

LKG7102D7:~# udevtest /sys/devices/platform/ixp4xx-beeper.4
...
import_uevent_var: import into environment: 'PHYSDEVBUS=platform'
import_uevent_var: import into environment: 'MODALIAS=platform:ixp4xx-beeper'

appeared after 0 loops
main: run: 'socket:/org/kernel/udev/monitor'
main: run: '/sbin/modprobe --use-blacklist platform:ixp4xx-beeper'

With this patch, depmod adds an alias line (see below) to
modules.alias which allows modprobe to load the right module.

This version brings proper quote tracking across lines, and brings the
handling of comments into the same mechanism ensuring nesting is correctly
handled.  It brings the usual flurry of fixes for false positives.  It also
brings a number of new checks.  The most contentious change will likely be
the checks for NR_CPUS as this throws some new warnings in kernel/sched.c.

Of note:
 - all new quote tracking across lines
 - all new comment tracking
 - new more direct, less ambigious wording for some warnings
 - recommends mutexes and completions over semaphores
 - recommends strict_strto* over simple_strto*
 - report on direct use of NR_CPUS

Andy Whitcroft (22):
      Version: 0.16
      string quote tracking should cross line boundaries
      check spacing round -> correctly across newlines
      checks for linux/ against asm/ include files should be warnings
      standardise on 'required' and 'prohibited'
      take the first end of condition when parsing statements
      values: cope with unbalanced brackets
      preprocessor #elif is not a function
      preprocessor #if should not trigger trailing statement checks
      test: allow us to limit output to a single error
      recommend real mutexes over semaphores
      asm checks should mirror those for __asm__
      warn on semaphores being used in place of completions
      trailing ; on control structure should ignore do {} while ();
      recommend strict_strtoX over simple_strtoX
      redo comment handling as a quote type
      use of NR_CPUS is normally wrong
      consistant spacing should only be about spaces
      if brace check suppression should only apply to the top-levels
      use tr/// to align spacing for operators
      move to using four parameter form of substr
      check and report modifications to include/asm

Current nobh_write_end() implementation ignore partial writes(copied < len)
case if page was fully mapped and simply mark page as Uptodate, which is
totally wrong because area [pos+copied, pos+len) wasn't updated explicitly in

As you can see file's page contains garbage from pagecache instead of zeros.
#TEST_CASE_END

Attached patch:
- Add sanity check BUG_ON in order to prevent incorrect usage by caller,
  This is function invariant because page can has buffers and in no zero
  *fadata pointer at the same time.
- Always attach buffers to page is it is partial write case.
- Always switch back to generic_write_end if page has buffers.
  This is reasonable because if page already has buffer then generic_write_begin
  was called previously.

Call mm_free_cgroup earlier.  Otherwise a reference due to lazy mm switching
can prevent cgroup removal.
