[git pull] vfs pile 1 (of many small ones this time ;-/)

[Al Viro <viro@ZenIV.linux.org.uk>]

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.  There
definitely will be a lot more (starting with Miklos' check_submount_and_drop()
series).  There's one trivial conflict in fs/dcache.c (lockref changes
affecting a context line), other than that this one should merge clean...

Please, pull from the usual place -
