# Merge: a782e8664972 50417d22d0ef
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'pull-work.dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull vfs dcache updates from Al Viro:
#      "The main part here is making parallel lookups safe for RT - making
#       sure preemption is disabled in start_dir_add()/ end_dir_add() sections
#       (on non-RT it's automatic, on RT it needs to to be done explicitly)
#       and moving wakeups from __d_lookup_done() inside of such to the end of
#       those sections.
#     
#       Wakeups can be safely delayed for as long as ->d_lock on in-lookup
#       dentry is held; proving that has caught a bug in d_add_ci() that
#       allows memory corruption when sufficiently bogus ntfs (or
#       case-insensitive xfs) image is mounted. Easily fixed, fortunately"
#     
#     * tag 'pull-work.dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       fs/dcache: Move wakeup out of i_seq_dir write held region.
#       fs/dcache: Move the wakeup from __d_lookup_done() to the caller.
#       fs/dcache: Disable preemption on i_dir_seq write side on PREEMPT_RT
#       d_add_ci(): make sure we don't miss d_lookup_done()
