====================
rxrpc, afs: Interruptibility fixes
Here are a number of fixes for AF_RXRPC and AFS that make AFS system calls
less interruptible and so less likely to leave the filesystem in an
uncertain state. There's also a miscellaneous patch to make tracing
consistent.
(1) Firstly, abstract out the Tx space calculation in sendmsg. Much the
same code is replicated in a number of places that subsequent patches
are going to alter, including adding another copy.
(2) Fix Tx interruptibility by allowing a kernel service, such as AFS, to
request that a call be interruptible only when waiting for a call slot
to become available (ie. the call has not taken place yet) or that a
call be not interruptible at all (e.g. when we want to do writeback
and don't want a signal interrupting a VM-induced writeback).
(3) Increase the minimum delay on MSG_WAITALL for userspace sendmsg() when
waiting for Tx buffer space as a 2*RTT delay is really small over 10G
ethernet and a 1 jiffy timeout might be essentially 0 if at the end of
the jiffy period.
(4) Fix some tracing output in AFS to make it consistent with rxrpc.
(5) Make sure aborted asynchronous AFS operations are tidied up properly
so we don't end up with stuck rxrpc calls.
(6) Make AFS client calls uninterruptible in the Rx phase. If we don't
wait for the reply to be fully gathered, we can't update the local VFS
state and we end up in an indeterminate state with respect to the
server.
