[SCSI] scsi: sd, sr, st, and scsi_lib all fail to copy cmd_len to new cmd
Timothy Thelin [Wed, 14 Sep 2005 02:56:28 +0000 (19:56 -0700)]
This fixes an issue in scsi command initialization from a request
where sd, sr, st, and scsi_lib all fail to copy the request's
cmd_len to the scsi command's cmd_len field.
