The whole set can be grabbed via anonymous cvs (empty password):

cvs -z3 -d:pserver:anonymous@cvs.cciss.sourceforge.net:/cvsroot/cciss co 2.5.44

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.
