| Subject: [PATCH] scsi: storvsc: properly handle SRB_ERROR when sense message |
| is present |
| |
| commit bba5dc332ec2d3a685cb4dae668c793f6a3713a3 upstream. |
| |
| When sense message is present on error, we should pass along to the upper |
| layer to decide how to deal with the error. |
| This patch fixes connectivity issues with Fiber Channel devices. |
