    Subjectscsi_reset requirement questions
    Date
    I am not clear on scsi_reset requirement.  Here are the questions:

    1, When scsi_reset called lower layer driver with SCSI_RESET_SYNCHRONOUS
    flag, should lower driver discard all commands since mid level
    driver will send all of them again (according to the comment in
    scsi_obsolete.c)? Or all command should be returned with DID_ERROR
    status through scsi_done?

    2, What happens if the flag is SCSI_RESET_ASYNCHRONOUS? Should
    lower driver process all command as usual afetr reset?

    3, Only SCSI_RESET_SUGGEST_HOST_RESET and SCSI_RESET_SUGGEST_BUS_RESET
    are available. What if device reset is required?

    Thanks!
