Pull vfs updates from Al Viro:
 "The big thing in this pile is Eric's unmount-on-rmdir series; we
  finally have everything we need for that.  The final piece of prereqs
  is delayed mntput() - now filesystem shutdown always happens on
  shallow stack.

  Other than that, we have several new primitives for iov_iter (Matt
  Wilcox, culled from his XIP-related series) pushing the conversion to
  ->read_iter()/ ->write_iter() a bit more, a bunch of fs/dcache.c
  cleanups and fixes (including the external name refcounting, which
  gives consistent behaviour of d_move() wrt procfs symlinks for long
  and short names alike) and assorted cleanups and fixes all over the
  place.

  This is just the first pile; there's a lot of stuff from various
  people that ought to go in this window.  Starting with
  unionmount/overlayfs mess...  ;-/"

reiserfs: Don't use MAXQUOTAS value

2014-09-17T09:59:12+00:00

MAXQUOTAS value defines maximum number of quota types VFS supports.
This isn't necessarily the number of types reiserfs supports and with
addition of project quotas these two numbers stop matching. So make
reiserfs use its private definition.

reiserfs: Fix use after free in journal teardown

2014-08-12T10:46:30+00:00

If do_journal_release() races with do_journal_end() which requeues
delayed works for transaction flushing, we can leave work items for
flushing outstanding transactions queued while freeing them. That
results in use after free and possible crash in run_timers_softirq().

Fix the problem by not requeueing works if superblock is being shut down
(MS_ACTIVE not set) and using cancel_delayed_work_sync() in
do_journal_release().

reiserfs: fix corruption introduced by balance_leaf refactor

2014-08-05T21:18:38+00:00

Commits f1f007c308e (reiserfs: balance_leaf refactor, pull out
balance_leaf_insert_left) and cf22df182bf (reiserfs: balance_leaf
refactor, pull out balance_leaf_paste_left) missed that the `body'
pointer was getting repositioned. Subsequent users of the pointer
would expect it to be repositioned, and as a result, parts of the
tree would get overwritten. The most common observed corruption
is indirect block pointers being overwritten.

Since the body value isn't actually used anymore in the called routines,
we can pass back the offset it should be shifted. We constify the body
and ih pointers in the balance_leaf as a mostly-free preventative measure.
