[git pull] vfs pile 3

[Al Viro]

Assorted cleanups and fixes; in "trivial API change" department - ->d_compare()
losing 'parent' argument.

I'm not sure if I'd taken the right approach with the last commit; the thing
is, fs/namei.c part has a trivial conflict with the userns changes already
in mainline *and* the posted patch had been against the mainline.  Sure,
I could apply it to this branch, resolve that conflict and let you resolve
the one that would induce on merge.  Or I could backmerge from the point
where userns changes went into mainline and apply as-is, with no conflicts
for anyone.  Or put it into a separate pull request after this pile gets
merged.

I went for the second variant (backmerge), but if you prefer the third one,
just pull #for-linus-2 and I'll send a separate pull request for the last
commit.  Or just cherry-pick that last commit from #for-linus after having
pulled #for-linus-2.
