4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Max Gurtovoy <maxg@xxxxxxxxxxxx> commit 0e12af84cdd3056460f928adc164f9e87f4b303b upstream. A copy/paste bug (probably) caused setting of an app_tag check mask in case where a ref_tag check was needed.
