From 4b6a32c070fe6aac6b1097a337fd66e8a792b9f4 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Fri, 24 Aug 2012 15:59:14 -0400 Subject: [PATCH] SELinux: do all flags twiddling in one place Currently we set the initialize and seclabel flag in one place. Do some unrelated printk then we unset the seclabel flag. Eww. Instead do the flag twiddling in one place in the code not seperated by unrelated printk. Also don't set and unset the seclabel flag. Only set it if we need to.
