Message

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 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".

  scsi: ufs: Change names related to error history
  scsi: ufs: Add fatal and auto-hibern8 error history
  scsi: ufs: Do not reset error history during host reset
  scsi: ufs: Add history of fatal events
