Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull final vfs updates from Al Viro: - The ->i_mutex wrappers (with small prereq in lustre) - a fix for too early freeing of symlink bodies on shmem (they need to be RCU-delayed) (-stable fodder) - followup to dedupe stuff merged this cycle * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: vfs: abort dedupe loop if fatal signals are pending make sure that freeing shmem fast symlinks is RCU-delayed wrappers for ->i_mutex access lustre: remove unused declaration
