Actually, I didn't. Error handling has its own separate entry into
->queuecommand() (scsi_send_eh_cmnd()), so it wouldn't be affected by my
changes.
My purpose is quite simple: Any normal block actions (read/write from
mounted fs, or CD burning via SG_IO) would be errored. Any special
commands (from ioctls, direct commands or stack generated) would not be
affected.
i.e.
REQ_CMD errors
REQ_BLOCK_PC errors
REQ_SPECIAL is allowed
James
