Most of that pile is LOOKUP_CACHED series; the rest is a couple of
misc cleanups in the general area...

	There's a minor bisect hazard in the end of series, and normally
I would've just folded the fix into the previous commit, but this branch is
shared with Jens' tree, with stuff on top of it in there, so that would've
required rebases outside of vfs.git.

	NOTE: I'm less than thrilled by the "let's allow offloading pathwalks
to helper threads" push, but LOOKUP_CACHED is useful on its own.
