[git pull] vfs.git fixes

[Al Viro]

	A couple of fixes (-stable fodder) + dead code removal after the
overlayfs fix; I agree that it's better to separate from the fix part
to make backporting easier, but IMO it's not worth delaying said dead
code removal until the next window.  Please, pull from

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Al Viro (2):
