From 97f8b87e9108485a0b7070645662253561304458 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Thu, 31 Jan 2013 21:51:47 +0100 Subject: tipc: remove redundant checking for the number of iovecs in a send request As the number of iovecs in a send request is already limited within UIO_MAXIOV(i.e. 1024) in __sys_sendmsg(), it's unnecessary to check it again in TIPC stack.
