From 257313b2a87795e07a0bdf58d0fffbdba8b31051 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 19 May 2011 21:22:53 -0700 Subject: selinux: avoid unnecessary avc cache stat hit count There is no point in counting hits - we can calculate it from the number of lookups and misses. This makes the avc statistics a bit smaller, and makes the code generation better too.
