There is one race issue between mevent callback (which is called in mevent_dispatch thread) and mevent_delete (which could be called in dev thread). And the callback is called after mevent_delete. libevent have the exactly same issue. The issue is decripted here: https://github.com/libevent/libevent/blob/master/whatsnew-2.1.txt The fixing is: We introduce a teardown callback to mevent and make sure there is no race issue between callback and teardown call. This patch updates the mevent API and the caller as well. Tracked-On: #1877 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com> Acked-by: Yu Wang <yu1.wang@intel.com>
