Looks like you missed one case that should change to KILLABLE?

Hmm ... guess we need a schedule_timeout_killable. This should probably
look like:
if (*timeout > NFS4_POLL_RETRY_MAX)
*timeout = NFS4_POLL_RETRY_MAX;
+ schedule_timeout_killable(*timeout);
+ if (fatal_signalled())
res = -ERESTARTSYS;
*timeout <<= 1;

Another missing KILLABLE.

wait_event_killable?
Anyway, none of these explain the non-killability of the *stat* calls.
