Hi, this patch 4/4 for pktcdvd against Linux 2.6.18 (stable) or 2.6.18-mm2 adds a sysfs and a debugfs interface. Also it adds the ability to control the bio write queue of the driver (write congestion control). For more infos see the Documentation/* files in the patch. You must first apply patch 1/4, 2/4 and 3/4 !
