From f004afe60db5b98f2b981978fde8a0d4c6298c5d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Sun, 15 Jun 2014 01:19:01 +0900 Subject: selinux: simple cleanup for cond_read_node() The node->cur_state and len can be read in a single call of next_entry(). And setting len before reading is a dead write so can be eliminated.
