[git pull] vfs pile 1

From: Al Viro
Date: Mon Jan 27 2014 - 09:25:32 EST


Assorted stuff; the biggest pile here is Christoph's ACL series.
Plus assorted cleanups and fixes all over the place... There will be
another pile later this week.

There's a couple of conflicts - rcupdate.h and posix_acl.h; proposed resolution
in vfs.git#conflict-resolution. Please, pull from the usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus
