commit 81e49f811404f428a9d9a63295a0c267e802fa12
Author: Glauber Costa
Date: Wed Aug 28 10:18:13 2013 +1000i915: bail out earlier when shrinker cannot acquire mutex
SHRINK_STOP was added to tell the core shrinker code to bail out and
go to the next shrinker since the i915 shrinker couldn't acquire
required locks. But the SHRINK_STOP return code was added to the
->count_objects callback and not the ->scan_objects callback as it
should have been, resulting in tons of dmesg noise likeshrink_slab: i915_gem_inactive_scan+0x0/0x9c negative objects to delete nr=-xxxxxxxxx
Fix discusssed with Dave Chinner.

Date: Thu Jun 13 00:54:58 2013 +0200drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms
Ville brough up the idea that this is just the pipe A quirk gone
wrong.Note that after resume the bios might or might not have enabled pipe A
already. We have a bit of magic to make sure that on resume we set up
a decent mode for pipe A, but I fear if I just smash pipe A to always
on we'd enable it in a bogus state and hang the hw. Hence the
readback.v2: Clarify the logic a bit as suggested by Chris. Also amend the
commit message to clarify why we don't unconditionally enable the
pipe.Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=66462

The native TV encoder has it's own flags to adjust sync modes and
enabled interlaced modes which are totally irrelevant for the adjusted
mode. This worked out nicely since the input modes used by both the
load detect code and reported in the ->get_modes callbacks all have no
flags set, and we also don't fill out any of them in the ->get_config
callback.This changed with the additional sanitation done with

Date: Tue Jul 30 13:36:32 2013 +0300drm/i915: make user mode sync polarity setting explicit
sinc now the "no flags at all" state wouldn't fit through core code
any more. So fix this up again by explicitly clearing the flags in the
->compute_config callback.Aside: We have zero checking in place to make sure that the requested
mode is indeed the right input mode we want for the selected TV mode.
So we'll happily fall over if userspace tries to pull us. But that's
definitely work for a different patch series. So just add a FIXME
comment for now.Reported-by: Knut Petersen

Author: Mika Kuoppala
Date: Thu May 23 13:55:35 2013 +0300drm/i915: avoid big kmallocs on reading error state
we introduce a two-pass mechanism for splitting long strings being
formatted into the error-state. The first pass finds the length, and the
second pass emits the right portion of the string into the accumulation
buffer. Unfortunately we use the same va_list for both passes, resulting
in the second pass reading garbage off the end of the argument list. As
the two passes are only used for boundaries between read() calls, the
corruption is only rarely seen.This fixes the root cause behind

First round of IIO fixes for 3.12
A series of wrong 'struct dev' assumptions in suspend/resume callbacks
following on from this issue being identified in a new driver review.
One to watch out for in future.A number of driver specific fixes
1) at91 - fix a overflow in clock rate computation
2) dummy - Kconfig dependency issue
3) isl29018 - uninitialized value
4) hmc5843 - measurement conversion bug introduced by recent cleanup.
5) ade7854-spi - wrong return value.Some IIO core fixes
1) Wrong value picked up for event code creation for a modified channel
2) A null dereference on failure to initialize a buffer after no buffer has
been in use, when using the available_scan_masks approach.
3) Sampling not stopped when a device is removed. Effects forced removal
such as hot unplugging.
4) Prevent device going away if a chrdev is still open in userspace.
5) Prevent race on chardev opening and device being freed.
6) Add a missing iio_buffer_init in the call back buffer.These last few are the first part of a set from Lars-Peter Clausen who
has been taking a closer look at our removal paths and buffer handling
than anyone has for quite some time. -

Users have been complaining of the uuid tree stuff warning that there is no uuid
root when trying to do snapshot operations. This is because if you mount -o ro
we will not create the uuid tree. But then if you mount -o rw,remount we will
still not create it and then any subsequent snapshot/subvol operations you try
to do will fail gloriously. Fix this by creating the uuid_root on remount rw if
it was not already there. Thanks,Signed-off-by: Josef Bacik

Commit 2bc5565286121d2a77ccd728eb3484dff2035b58 (Btrfs: don't update atime on
RO subvolumes) ensures that the access time of an inode is not updated when
the inode lives in a read-only subvolume.
However, if a directory on a read-only subvolume is accessed, the atime is
updated. This results in a write operation to a read-only subvolume. I
believe that access times should never be updated on read-only subvolumes.To reproduce:
