[OpenAFS] Fwd: Bug#430179: Oops loading openafs module on kernel 2.6.22-rc3

Bcc'd to bugs.

Looks like we still don't have everything quite right for 2.6.22, or I
didn't pull up enough.  I pulled up various patches from the current
STABLE CVS around the build logic, but is there another that I missed?

Package: openafs-modules-source
Version: 1.4.4.dfsg1-4

On Ubuntu gutsy amd64 with kernel 2.6.22-6-generic (2.6.22-rc3), the
openafs module now compiles (yay!) but causes a kernel oops when loaded:
