Oooh, much better. I was foolishly trying to fix all the lock_kernels()
in the original write_ports().
There are some comments in net/sunrpc/svc.c referring to callers needing
to own the BKL, which will need updating also. Otherwise, looks good :-)
Perhaps the trouble I was having was in the older codebase only, or
because I didn't pull the locking out far enough.
