joerg 1997/12/26 06:52:30 PST Modified files: sys/scsi worm.c Log: Fix some breakage that prevented the Plasmon burners from being used under -current. The actual preparation of the next track will now be deferred until just before the first write operation. Otherwise, opening the device with write intent will cause the execution of commands that are illegal in `limited command set mode' (i.e., after the write channel has been opened). While i was at it, cleaned up the worm_open() function a bit. Removed the volume overflow pre-check in worm_strategy(). It was time-consuming, and rather useless in many cases anyway (with the size being reported for just the entire volume only), so we can as well let the actual SCSI command fail instead, where it'll properly be reported as EIO. Partially submitted by & discussed with: jmz Revision Changes Path 1.50 +66 -67 src/sys/scsi/worm.c
