#     afs: Fix missing timeout reset
#     
#     In afs_wait_for_call_to_complete(), rather than immediately aborting an
#     operation if a signal occurs, the code attempts to wait for it to
#     complete, using a schedule timeout of 2*RTT (or min 2 jiffies) and a
#     check that we're still receiving relevant packets from the server before
#     we consider aborting the call.  We may even ping the server to check on
#     the status of the call.
#     
#     However, there's a missing timeout reset in the event that we do
#     actually get a packet to process, such that if we then get a couple of
#     short stalls, we then time out when progress is actually being made.
#     
#     Fix this by resetting the timeout any time we get something to process.
#     If it's the failure of the call then the call state will get changed and
#     we'll exit the loop shortly thereafter.
#     
#     A symptom of this is data fetches and stores failing with EINTR when
#     they really shouldn't.
#
