From f1c6381a6e337adcecf84be2a838bd9e610e2365 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 12 Feb 2009 14:50:54 -0500 Subject: SELinux: remove unused av.decided field It appears there was an intention to have the security server only decide certain permissions and leave other for later as some sort of a portential performance win. We are currently always deciding all 32 bits of permissions and this is a useless couple of branches and wasted space. This patch completely drops the av.decided concept. This in a 17% reduction in the time spent in avc_has_perm_noaudit based on oprofile sampling of a tbench benchmark.
