This patchset provides more information of fatal errros and auto-hibern8 errors to improve debugging by keeping their error history as completed as possible. Thanks Avri so much for prompt reviewing patchset v1. I would like to post new version to add one more patch "scsi: ufs: Add history of fatal events" to provide history for "non-interrupt-based" errors and abnormal events as well.
