From 048ed4b6266144fdee55089c9eef55b0c1d42ba1 Mon Sep 17 00:00:00 2001 From: wangweidong Date: Tue, 21 Jan 2014 15:44:11 +0800 Subject: [PATCH] sctp: remove macros sctp_{lock|release}_sock Redefined {lock|release}_sock to sctp_{lock|release}_sock for user space friendly code which we haven't use in years, so removing them.
