"The first part makes sure we don't hold up umount with pending async

The second part prepares for a cleanup of the fuse device I/O code by
adding a helper for simple request submission, with some savings in

In bio-based DM's clone_endio(), when target_type doesn't implement
.end_io (e.g. linear) r will be always be initialized 0. So if a
WRITE SAME bio fails WRITE SAME will not be disabled as intended.
Fix this by initializing r to error, rather than 0, in clone_endio().

Currently userspace is allowed to pass in basiclly any kind of garbage
to setcrtc. Try to catch the cases where the timings make no sense
by passing the mode through drm_mode_validate_basic().
One concern here is that we now start to block some modes that have
worked in the past. It's at least possible with when using i915 with
LVDS/eDP. Previously we've just ignored everything but hdisplay/vdisplay
from the user mode and just overwritten the rest with the panel fixed
mode. So if someone has been passing a mode with just those populated
that would now stop working. If that is a real problem, we can't add
these checks to the core code and each driver would have to have its
own sanity checks. So fingers crossed...

Make sure the timings of probed modes at least pass some very basic
sanity checks.
The checks include:
- clock,hdisplay,vdisplay are non zero
- sync pulse fits within the blanking period
- htotal,vtotal are big enough
I have not checked all the drivers to see if the modes the generate
might violate these constraints. I'm hoping not, because that would mean
either abandoning the idea of doing this from the core code, or fixing
the drivers.
I'm not entirely sure about limiting the sync pulse to the blanking
period. Intel hardware doesn't support such things, but some other
hardware might. However at least HDMI doesn't allow having sync pulse
edges within the active period, so I'm thinking the check is probably
OK to have in the common code.

Make drm_mode_validate_size() and drm_mode_validate_flag() deal with a
single mode instead of having each iterate through the mode list.
The hope is that in the future we might be able to share various mode
validation functions between modeset and get_modes.

After converting inline data to normal data, client need to flush
the new i_inline_version (CEPH_INLINE_NONE) to MDS. This commit makes
cap messages (sent to MDS) contain inline_version and inline_data.
Client always converts inline data to normal data before data write,
so the inline data length part is always zero.

Before any data write, convert inline data to normal data and set
i_inline_version to CEPH_INLINE_NONE. The OSD request that saves

old data overwrites newer data.

Current snaphost code does not properly handle moving inode from one
empty snap realm to another empty snap realm. After changing inode's
snap realm, some dirty pages' snap context can be not equal to inode's
i_head_snap. This can trigger BUG() in ceph_put_wrbuffer_cap_refs()
The fix is introduce a global empty snap context for all empty snap
realm. This avoids triggering the BUG() for filesystem with no snapshot.

After creating/deleting/renaming file, offsets of sibling dentries may
change. So we can not use cached dentries to satisfy readdir. But we can
still use the cached dentries to conclude -ENOENT for lookup.
This patch introduces a new inode flag indicating if child dentries are
ordered. The flag is set at the same time marking a directory complete.
After creating/deleting/renaming file, we clear the flag on directory
inode. This prevents ceph_readdir() from using cached dentries to satisfy
readdir syscall.

When a lock operation is interrupted, current code sends a unlock request to
MDS to undo the lock operation. This method does not work as expected because
the unlock request can drop locks that have already been acquired.
The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR
requests to interrupt blocked file lock request. These requests do not drop
locks that have alread been acquired, they only interrupt blocked file lock
request.

Commit 80e96c5484be ("dm thin: do not allow thin device activation
while pool is suspended") delayed the initialization of a new thin
device's refcount and completion until after this new thin was added
to the pool's active_thins list and the pool lock is released. This
opens a race with a worker thread that walks the list and calls
thin_get/put, noticing that the refcount goes to 0 and calling
complete, freezing up the system and giving the oops below:

are released
Discard bios and thin device deletion have the potential to release data
blocks. If the thin-pool is in out-of-data-space mode, and blocks were
released, transition the thin-pool back to full write mode.
The correct time to do this is just after the thin-pool metadata commit.
It cannot be done before the commit because the space maps will not
allow immediate reuse of the data blocks in case there's a rollback
following power failure.

When the pool was in PM_OUT_OF_SPACE mode its process_prepared_discard
function pointer was incorrectly being set to
process_prepared_discard_passdown rather than process_prepared_discard.
This incorrect function pointer meant the discard was being passed down,
but not effecting the mapping. As such any discard that was issued, in
an attempt to reclaim blocks, would not successfully free data space.
