Sorry that my changes got you confused and thank you for help resolve 
conflicts. My change ("scsi: ufs: Abort tasks before clearing them from
doorbell") is to serve my fixes to ufs error recovery which only got 
up on scsi-queue-5.10. So I checked out to scsi-queue-5.10 and made my
changes on the tip of scsi-queue-5.10, below 2 changes were not even
present in scsi-queue-5.10 back that time.

scsi: ufs: Clean up completed request without interrupt notification
scsi: ufs: No need to send Abort Task if the task in DB was cleared

Is there anything wrong with my work flow above? Please let me know the
right process so that I can avoid such conflicts in my next changes, 
also touch the func ufshcd_abort(). Thanks!


Can Guo.
