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!
