From 80b45261a0b263536b043c5ccfc4ba4fc27c2acc Mon Sep 17 00:00:00 2001 From: Simon Derr Date: Fri, 21 Jun 2013 15:32:43 +0200 Subject: 9P: Add cancelled() to the transport functions. RDMA needs to post a buffer for each incoming reply. Hence it needs to keep count of these and needs to be aware of whether a flushed request has received a reply or not. This patch adds the cancelled() callback to the transport modules. It is called when RFLUSH has been received and that the corresponding request will never receive a reply.
