This is normally true, but not always : when using RDMA, req->rc will temporarily be set to NULL after the request has been sent. That is usually OK though, as when the reply arrives, req->rc will be reassigned to a sane value before the request is recycled. But there is a catch : if the request is flushed, the reply will never arrive, and req->rc will be NULL, but not req->tc. This patch fixes p9_tag_alloc to take this into account.
