Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs fixes from Al Viro:
"Assorted fixes.
Some of that is only a matter with fault injection (broken handling of
small allocation failure in various mount-related places), but the
last one is a root-triggerable stack overflow, and combined with
userns it gets really nasty ;-/"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
Don't leak MNT_INTERNAL away from internal mounts
mm,vmscan: Allow preallocating memory for register_shrinker().
rpc_pipefs: fix double-dput()
orangefs_kill_sb(): deal with allocation failures
jffs2_kill_sb(): deal with failed allocations
hypfs_kill_super(): deal with failed allocations
