Previously we pre-allocate cap release messages for each caps. This
wastes lots of memory when there are large amount of caps. This patch
make the code not pre-allocate the cap release messages. Instead,
we add the corresponding ceph_cap struct to a list when releasing a
cap. Later when flush cap releases is needed, we allocate the cap
release messages dynamically.

When ceph inode's i_head_snapc is NULL, __ceph_mark_dirty_caps()
accesses snap realm's cached_context. So we need take read lock
of snap_rwsem.

when a snap notification contains no new snapshot, we can avoid
sending FLUSHSNAP message to MDS. But we still need to create
cap_snap in some case because it's required by write path and
page writeback path

In most cases that snap context is needed, we are holding
reference of CEPH_CAP_FILE_WR. So we can set ceph inode's
i_head_snapc when getting the CEPH_CAP_FILE_WR reference,
and make codes get snap context from i_head_snapc. This makes
the code simpler.
Another benefit of this change is that we can handle snap
notification more elegantly. Especially when snap context
is updated while someone else is doing write. The old queue
cap_snap code may set cap_snap's context to ether the old
context or the new snap context, depending on if i_head_snapc
is set. The new queue capp_snap code always set cap_snap's
context to the old snap context.

Cached_context in ceph_snap_realm is directly accessed by
uninline_data() and get_pool_perm(). This is racy in theory.
both uninline_data() and get_pool_perm() do not modify existing
object, they only create new object. So we can pass the empty
snap context to them. Unlike cached_context in ceph_snap_realm,
we do not need to protect the empty snap context.

page_cache_read, do_generic_file_read, __generic_file_splice_read and
__ntfs_grab_cache_pages currently ignore mapping_gfp_mask when calling
add_to_page_cache_lru which might cause recursion into fs down in the
direct reclaim path if the mapping really relies on GFP_NOFS semantic.
This doesn't seem to be the case now because page_cache_read (page fault
path) doesn't seem to suffer from the reclaim recursion issues and
do_generic_file_read and __generic_file_splice_read also shouldn't be
called under fs locks which would deadlock in the reclaim path. Anyway it
is better to obey mapping gfp mask and prevent from later breakage.

Allowing watchdog threads to be parked means that we now have the
opportunity of actually seeing persistent parked threads in the output
of /proc/<pid>/stat and /proc/<pid>/status. The existing code reported
such threads as "Running", which is kind-of true if you think of the
case where we park them as part of taking cpus offline. But if we allow
parking them indefinitely, "Running" is pretty misleading, so we report
them as "Sleeping" instead.
We could simply report them with a new string, "Parked", but it feels
like it's a bit risky for userspace to see unexpected new values; the
output is already documented in Documentation/filesystems/proc.txt, and
it seems like a mistake to change that lightly.
The scheduler does report parked tasks with a "P" in debugging output
from sched_show_task() or dump_cpu_task(), but that's a different API.
Similarly, the trace_ctxwake_* routines report a "P" for parked tasks,
but again, different API.
This change seemed slightly cleaner than updating the task_state_array
to have additional rows. TASK_DEAD should be subsumed by the exit_state
bits; TASK_WAKEKILL is just a modifier; and TASK_WAKING can very
reasonably be reported as "Running" (as it is now). Only TASK_PARKED
shows up with unreasonable output here.

ocfs2_rotate_tree_left() calls __ocfs2_rotate_tree_left() for left
rotation while non-rightmost path containing an empty extent in the leaf
block. __ocfs2_rotate_tree_left() returns -EAGAIN if right subtree having an
empty extent and pass the empty_extent_path to caller. The caller
ocfs2_rotate_tree_left() will restart rotation from the returned path.
It will trigger the BUG_ON(!ocfs2_is_empty_extent) when the et on disk
is as follows:
eb0 is the leaf block of path(say path_a) passed to
ocfs2_rotate_tree_left, which has an empty rec[0].
eb1 is the leaf block of path(say path_b) that just right to path_a, which
has no empty record.
eb2 is the leaf block of path(say path_c) that just right to path_b, which
has an empty rec[0]. And path_c is also the rightmost path.
Now we want to remove the empty rec[0] in eb0:
ocfs2_rotate_tree_left:
-> call __ocfs2_rotate_tree_left with path_a as its input *path*
-> call ocfs2_rotate_subtree_left with path_a as its input
*left_path* and path_b as its input *right_path*. it will move
rec[0] in eb1 to eb0, and rec[0] in eb0 is not empty now.
-> continue to call ocfs2_rotate_subtree_left with path_b as its
input *left_path* and path_c as its input *right_path*, and
return -EAGAIN because eb2 has an empty rec[0]
-> call __ocfs2_rotate_tree_left with path_c as it input, rotate all
records in eb2 to left and return 0.
-> call __ocfs2_rotate_tree_left with path_a as its input, and triggers
the BUG_ON(!ocfs2_is_empty_extent) as the rec[0] in eb0 is not empty.
So the BUG_ON() should be removed and return 0 if rec[0] is no longer an
empty extent.

It fills in the generic part of LAYOUTSTATS call. One thing to note
is that we don't really track if IO is continuous or not. So just fake
to use the completed bytes for it.
Still missing flexfiles specific part, which will be included in the next patch.

So that we can report cumulative time since the beginning
of statistics collection of the layout.

Pull MTD updates from Brian Norris:
"JFFS2:
- fix a theoretical unbalanced locking issue; the lock handling was a
bit unclean, but AFAICT, it didn't actually lead to real deadlocks
NAND:
- brcmnand driver: new driver supporting NAND controller found
originally on Broadcom STB SoCs (BCM7xxx), but now also found on
BCM63xxx, iProc (e.g., Cygnus, BCM5301x), BCM3xxx, and more
- begin factoring out BBT code so it can be shared between
traditional (parallel) NAND drivers and upcoming SPI NAND drivers
(WIP)
- add common DT-based init support, so nand_base can pick up some
flash properties automatically, using established common NAND DT
properties
- mxc_nand: support 8-bit ECC
- pxa3xx_nand:
* fix build for ARM64
* use a jiffies-based timeout
SPI NOR:
- add a few new IDs
- clear out some unnecessary entries
- make sure SECT_4K flags are correct for all (?) entries
Core:
- fix mtd->usecount race conditions (BUG_ON())
- switch to modern PM ops
Other:
- CFI: save code space by de-inlining large functions
- clean up some partition parser selection code across several
drivers
- various miscellaneous changes, mostly minor"

dir_pages was declared in a lot of filesystems.
Use newly dir_pages() from pagemap.h
