Revision eb4aec84d6bdf98d00cedb41c18000f7a31e648a authored by Zefan Li on 18 September 2014, 09:28:46 UTC, committed by Tejun Heo on 18 September 2014, 16:32:52 UTC
cgroup_pidlist_start() holds cgrp->pidlist_mutex and then calls pidlist_array_load(), and cgroup_pidlist_stop() releases the mutex. It is wrong that we release the mutex in the failure path in pidlist_array_load(), because cgroup_pidlist_stop() will be called no matter if cgroup_pidlist_start() returns errno or not.
