The kernel I saw this on does indeed include that patch. I'll try to
back it out (probably not before tomorrow evening, though).
My original description was inaccurate in a few respects: mounting /afs
works fine, it's the first attempt to open the directory afterwards that
oopses. And I hadn't noticed a third lock in crref()/crfree(). Here's
the relevant log excerpt:
Unable to handle kernel NULL pointer dereference at 0000000000000000

inotify, indeed. You were correct. Thanks.
