[git pull] vfs misc pile

[Al Viro]

	Assorted stuff all over the place (the largest group here is
Christoph's stat cleanups).  This is probably the last pull request
for this window - there's also a group of sparc patches in -next,
and davem seemed to be OK with that at the time, but I'd rather have
it go through his tree when he's back - nothing urgent in that series.
