On my debian stable system, it looks like every device gets its parent looked up in sysfs. I think this is due to SUBSYSTEMS matches. I see the udev default rules are different, but it looks like they still test for SUBSYSTEMS on every single device: SUBSYSTEMS=="scsi", ATTRS{type}=="1|8", GROUP="tape" SUBSYSTEMS=="scsi", ATTRS{type}=="4|5", GROUP="cdrom" SUBSYSTEMS=="scsi", ATTRS{type}=="0", GROUP="disk" Should we add SUBSYSTEM="scsi_generic" to these three rules?Sounds good. I think the "tape" will need a match for the actual scsi-tape devices too? The real "cdrom" and "disk" devices seems covered by explicit rules.
Yes, good catch. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
