From 4a93f5095a628d812b0b30c16d7bacea1efd783c Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 12 Mar 2014 09:43:17 +0100 Subject: flowcache: Fix resource leaks on namespace exit. We leak an active timer, the hotcpu notifier and all allocated resources when we exit a namespace. Fix this by introducing a flow_cache_fini() function where we release the resources before we exit.
