net: Remove iocb argument from sendmsg and recvmsg 2015-03-02T18:06:31+00:00 Ying Xue ying.xue@windriver.com 2015-03-02T07:37:48+00:00 1b784140474e4fc94281a49e96c67d29df0efbde After TIPC doesn't depend on iocb argument in its internal implementations of sendmsg() and recvmsg() hooks defined in proto structure, no any user is using iocb argument in them at all now.
