Pull core block IO changes from Jens Axboe:
"The major piece in here is the immutable bio_ve series from Kent, the
rest is fairly minor. It was supposed to go in last round, but
various issues pushed it to this release instead. The pull request
contains:
- Various smaller blk-mq fixes from different folks. Nothing major
here, just minor fixes and cleanups.
- Fix for a memory leak in the error path in the block ioctl code
from Christian Engelmayer.
- Header export fix from CaiZhiyong.
- Finally the immutable biovec changes from Kent Overstreet. This
enables some nice future work on making arbitrarily sized bios
possible, and splitting more efficient. Related fixes to immutable
bio_vecs:
- dm-cache immutable fixup from Mike Snitzer.
- btrfs immutable fixup from Muthu Kumar.
- bio-integrity fix from Nic Bellinger, which is also going to stable"

Immutable biovecs are going to require an explicit iterator. To
implement immutable bvecs, a later patch is going to add a bi_bvec_done
member to this struct; for now, this patch effectively just renames
things.

The versioning information is confusing for end-users. The numbers are
stuck at 1.5.0 when the tools version have moved to 1.8.2. Remove the
versioning system in the OCFS2 modules and let the kernel version be the
guide to debug issues.

In o2hb_shutdown_slot() and o2hb_check_slot(), since event is defined as
local, it is only valid during the call stack. So the following tiny race
case may happen in a multi-volumes mounted environment:
o2hb-vol1 o2hb-vol2
1) o2hb_shutdown_slot
allocate local event1
2) queue_node_event
add event1 to global o2hb_node_events
3) o2hb_shutdown_slot
allocate local event2
4) queue_node_event
add event2 to global o2hb_node_events
5) o2hb_run_event_list
delete event1 from o2hb_node_events
6) o2hb_run_event_list
event1 empty, return
7) o2hb_shutdown_slot
event1 lifecycle ends
8) o2hb_fire_callbacks
event1 is already *invalid*
This patch lets it wait on o2hb_callback_sem when another thread is firing
callbacks. And for performance consideration, we only call
o2hb_run_event_list when there is an event queued.

There may exist NULL pointer dereference in config_item_name() when one
volume (say Volume A) unmounts while another (say Volume B) mounting.
Volume A Volume B
already Mounted.
Unmounting, call
o2hb_heartbeat_group_drop_item()
-> config_item_put(item)
set reg(A)->item.ci_name to NULL
in function config_item_cleanup().
begin mounting, call
o2hb_region_pin() and tranverse all
regions. When reading
reg(A)->item.ci_name, it causes
NULL pointer dereference.
call o2hb_region_release() and
del reg(A) from list.
So we should skip accessing regions that is going to release when
tranverse o2hb_all_regions.

Under heavy I/O load, writing the disk heartbeat can be forced to wait for
minutes, and this causes the node to be fenced.
This patch tries to use WRITE_SYNC in submitting the heartbeat bio, so
that writing the heartbeat will have a priority over other requests.

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs update from Al Viro:
- big one - consolidation of descriptor-related logics; almost all of
that is moved to fs/file.c
(BTW, I'm seriously tempted to rename the result to fd.c. As it is,
we have a situation when file_table.c is about handling of struct
file and file.c is about handling of descriptor tables; the reasons
are historical - file_table.c used to be about a static array of
struct file we used to have way back).
A lot of stray ends got cleaned up and converted to saner primitives,
disgusting mess in android/binder.c is still disgusting, but at least
doesn't poke so much in descriptor table guts anymore. A bunch of
relatively minor races got fixed in process, plus an ext4 struct file
leak.
- related thing - fget_light() partially unuglified; see fdget() in
there (and yes, it generates the code as good as we used to have).
- also related - bits of Cyrill's procfs stuff that got entangled into
that work; _not_ all of it, just the initial move to fs/proc/fd.c and
switch of fdinfo to seq_file.
- Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts. The rest is a separate
pile, this was just a mechanical code movement.
- a few misc patches all over the place. Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree)."
Fix up trivial conflicts in the android binder driver, and some fairly
simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

flush[_delayed]_work_sync() are now spurious. Mark them deprecated
and convert all users to flush[_delayed]_work().
If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.
This patch doesn't make any functional difference.

the socket with it will forcibly reuse everyone else's port.

Currently if the heartbeat device is hard-ro, the o2hb thread keeps chugging
along and dumping errors along the way. The user needs to manually stop the
heartbeat.
The patch addresses this shortcoming by adding a limit to the number of times
the hb thread will iterate in an unsteady state. If the hb thread does not
ready steady state in that many interation, the start is aborted.

These files were getting <linux/module.h> via an implicit include

time during compiles of processing thousands of lines of headers

If o2hb finds unexpected values in the heartbeat slot, it prints a message
"ERROR: Device "dm-6": another node is heartbeating in our slot!"
This message could be misleading. This patch adds two more messages to
help users better diagnose the problem.

We have seen isolated cases (very few, I might add) of o2hb not detecting all
live nodes on startup. One plausible reasoning for it is that other node had
a hb io delay at the same time. The live threshold set at 2 (as low as it can
be) could be increased to ameliorate the situation.
But increasing the threshold directly affects mount time. Currently it takes
around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing
the threshold will make mounts even slower. As the issue itself is rare, we have
left things as they are for the local heartbeat mode.
However we can improve the situation for global heartbeat mode as in that mode,
we start the heartbeat much before the mount.
This patch doubles the live threshold for the start of the first region in
global heartbeat mode.
Addresses internal Oracle bug#10635585.
