From 615e51fdda6f274e94b1e905fcaf6111e0d9aa20 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Thu, 26 Jun 2014 14:33:56 -0400 Subject: selinux: reduce the number of calls to synchronize_net() when flushing caches When flushing the AVC, such as during a policy load, the various network caches are also flushed, with each making a call to synchronize_net() which has shown to be expensive in some cases. This patch consolidates the network cache flushes into a single AVC callback which only calls synchronize_net() once for each AVC cache flush.
