| Subject: IB/isert: fix T10-pi check mask setting |
| |
| 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") |
