To: linux-kernel; +Cc: Douglas Gilbert, James E.J. Bottomley
From: Randy Dunlap <randy.dunlap@oracle.com>
Change torque.net references for SCSI drivers & tools to their current
locations (sg.danny.cz/sg). Remove whitespace at ends of lines.
Same could be done for parport references at torque.net except that
those files don't seem to have a home now.
