From 8d0c2224ca6e04ba51c403805e7e1e2ca536520b Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 15 Jan 2014 10:45:28 +0900 Subject: [PATCH] tools lib traceevent: Make plugin unload function receive pevent The PEVENT_PLUGIN_UNLOADER function might need some cleanup using pevent like unregister some handlers. So pass pevent as argument.
