#     Merge branch 'next.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull autofs updates from Al Viro:
#      "autofs misuses checks for ->d_subdirs emptiness; the cursors are in
#       the same lists, resulting in false negatives. It's not needed anyway,
#       since autofs maintains counter in struct autofs_info, containing 0 for
#       removed ones, 1 for live symlinks and 1 + number of children for live
#       directories, which is precisely what we need for those checks.
#     
#       This series switches to use of that counter and untangles the crap
#       around its uses (it needs not be atomic and there's a bunch of
#       completely pointless "defensive" checks).
#     
#       This fell out of dcache_readdir work; the main point is to get rid of
#       ->d_subdirs abuses in there. I've more followup cleanups, but I hadn't
#       run those by Ian yet, so they can go next cycle"
#     
#     * 'next.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       autofs: don't bother with atomics for ino->count
#       autofs_dir_rmdir(): check ino->count for deciding whether it's empty...
#       autofs: get rid of pointless checks around ->count handling
#       autofs_clear_leaf_automount_flags(): use ino->count instead of ->d_subdirs
