4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: tang.junhui <[email protected]> commit 1fdd14279eab2e9f79745631379f0c53cb8f9a5a upstream. Reference count of pg leaks in alua_rtpg_work() since kref_put() is not called to decrease the reference count of pg when the condition pg->rtpg_sdev==NULL satisfied (actually it is easy to satisfy), it would cause memory of pg leakage.
