    scsi,block: update SCSI to handle mixed merge failures · da6c5c72
    Tejun Heo authored
    Update scsi_io_completion() such that it only fails requests till the
    next error boundary and retry the leftover.  This enables block layer
    to merge requests with different failfast settings and still behave
    correctly on errors.  Allow merge of requests of different failfast
    As SCSI is currently the only subsystem which follows failfast status,
    there's no need to worry about other block drivers for now.
