Volatile controls can change their value outside the v4l-ctrl framework.
We should ignore the cached written value of the ctrl when evaluating if
we should run s_ctrl.

We migrate a task using TASK_ON_RQ_MIGRATING state of on_rq:
raw_spin_lock(&old_rq->lock);
deactivate_task(old_rq, p, 0);
p->on_rq = TASK_ON_RQ_MIGRATING;
set_task_cpu(p, new_cpu);
raw_spin_unlock(&rq->lock);
I.e.:
write TASK_ON_RQ_MIGRATING
Place it in sched.h, because dl_task_timer() needs it.
Also remove lockdep check, which is not fit to this
function.

This patch implements fallocate's FALLOC_FL_INSERT_RANGE for XFS.
1) Make sure that both offset and len are block size aligned.
2) Update the i_size of inode by len bytes.
3) Compute the file's logical block number against offset. If the computed
block number is not the starting block of the ex
This commit adds fallocate FALLOC_FL_INSERT_RANGE support for fsx.

FALLOC_FL_INSERT_RANGE command is the opposite command of
FALLOC_FL_COLLAPSE_RANGE that is needed for advertisers or someone who want to
add some data in the middle of file. FALLOC_FL_INSERT_RANGE will create space
for writing new data within a file after shifting extents to right as given
length.

Your commit 96976c3d9aff ("drm/exynos: Add DECON driver") is included in
today's linux-next (ie, next-20150217). I noticed because a script I use
to check linux-next spotted a problem with it.
It added an (optional) dependency on DRM_EXYNOS7DECON instead of
