From 1b784140474e4fc94281a49e96c67d29df0efbde Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Mon, 2 Mar 2015 15:37:48 +0800 Subject: net: Remove iocb argument from sendmsg and recvmsg 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. Then we can drop the redundant iocb argument completely from kinds of implementations of both sendmsg() and recvmsg() in the entire networking stack.
