I never got any comment back on this. In order for udev to use the existing attribute, it needs to be moved out of the scsi_host device, and udev needs patched to handle bitwise comparisons, or my simple patch adding the new attribute can be applied. Are you certain you do not want to add a new attribute, and if so, would you accept a patch moving the existing one out of the scsi_host device so it will be a proper ancestor of the disk device? Kay Sievers thinks that the current location of scsi_host is broken should be fixed, but I think that involves significant changes to the scsi layer so I found that this patch was much simpler.
