Hmm. Eric - mind testing current -git?

J. R. Okajima found a possible problem with the new RCU filename
lookup, which could corrupt the filp_cache. I'd expect the normal
result to be an oops, but maybe there could be memory corruption. And
the easiest way to trigger it would probably be to have lots of
concurrent fs activity with renames.

Now, it's not new to -rc4: the whole rcu lookup thing was merged into
-rc1. But since I still don't see anything that looks likely to be
introduced after -rc3, it might not hurt to think that maybe it's just
rare enough that you just thought -rc3 was ok, and then you were
unlucky with -rc4.
