Thanks Avri so much for prompt reviewing patchset v1. I would like to post v2 to add one more patch "scsi: ufs: Add history of fatal events" to add history for "non-interrupt-based" errors as well, for example, - Link startup fail - Suspend fail - Resume fail - Task or request abort event Changes in v2: - Add new patch "scsi: ufs: Add history of fatal events".
