It had better not be. If it is, then I want to know where so that we
can fix it.
req->rq_xprt is set up when the request is initialized. It
is not meant to change until the request gets released. This again
should not happen while the request is still on the wait queue.
IOW the fix you propose would just be papering over another problem.
Cheers,
Trond
