For the cciss driver: This patch makes scsi commands to tape drives have no timeouts. Previously the timeout was 1000 seconds, too short, and nothing good happens when the timeout expires. Better to have no timeout. e.g. mt -f /dev/st0 erase may take about 2 hours 30 min on AIT 100. (patch 7 of 11)
