3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gao Feng <gfree.w...@vip.163.com>
[ Upstream commit f02b2320b27c16b644691267ee3b5c110846f49e ]
The mutex_destroy only makes sense when enable DEBUG_MUTEX. For the
good readbility, it's better to invoke it in exit func when the init
func invokes mutex_init.
