Merge tag 'for-linus-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs
Pull 9p changes from Eric Van Hensbergen: "A bunch of updates and cleanup within the transport layer, particularly with a focus on RDMA" * tag 'for-linus-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs: 9pnet_rdma: check token type before int conversion 9pnet: trans_fd : allocate struct p9_trans_fd and struct p9_conn together. 9pnet: p9_client->conn field is unused. Remove it. 9P: Get rid of REQ_STATUS_FLSH 9pnet_rdma: add cancelled() 9pnet_rdma: update request status during send 9P: Add cancelled() to the transport functions. net: Mark function as static in 9p/client.c 9P: Add memory barriers to protect request fields over cb/rpc threads handoff
