Merge branch 'work.sendmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs sendmsg updates from Al Viro: "More sendmsg work. This is a fairly separate isolated stuff (there's a continuation around lustre, but that one was too late to soak in -next), thus the separate pull request" * 'work.sendmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: ncpfs: switch to sock_sendmsg() ncpfs: don't mess with manually advancing iovec on send ncpfs: sendmsg does *not* bugger iovec these days ceph_tcp_sendpage(): use ITER_BVEC sendmsg afs_send_pages(): use ITER_BVEC rds: remove dead code ceph: switch to sock_recvmsg() usbip_recv(): switch to sock_recvmsg() iscsi_target: deal with short writes on the tx side [nbd] pass iov_iter to nbd_xmit() [nbd] switch sock_xmit() to sock_{send,recv}msg() [drbd] use sock_sendmsg()
