3.16.61-rc1 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.
Fixes: 38a2d0d429f1 ("IB/isert: convert to the generic RDMA READ/WRITE API")
Fixes: 9e961ae73c2c ("IB/isert: Support T10-PI protected transactions")
