Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc vfs fixes from Al Viro:
"Assorted fixes all over the place; some of that is -stable fodder,
some regressions from the last window"
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
ecryptfs_lookup_interpose(): lower_dentry->d_parent is not stable either
ecryptfs_lookup_interpose(): lower_dentry->d_inode is not stable
ecryptfs: fix unlink and rmdir in face of underlying fs modifications
audit_get_nd(): don't unlock parent too early
exportfs_decode_fh(): negative pinned may become positive without the parent locked
cgroup: don't put ERR_PTR() into fc->root
autofs: fix a leak in autofs_expire_indirect()
aio: Fix io_pgetevents() struct __compat_aio_sigset layout
fs/namespace.c: fix use-after-free of mount in mnt_warn_timestamp_expiry()
