Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs pile 1 from Al Viro: "Unfortunately, this merge window it'll have a be a lot of small piles - my fault, actually, for not keeping #for-next in anything that would resemble a sane shape ;-/ This pile: assorted fixes (the first 3 are -stable fodder, IMO) and cleanups + %pd/%pD formats (dentry/file pathname, up to 4 last components) + several long-standing patches from various folks.
