It will be going away as soon as I get around to writing the patch for it. Putting the sg symlink in there is not the proper place. For scsi generic you should create a scsi generic class (scsi_generic?) and create the individual sg devices in that directory (feel free to use the simple_class.c code that is currently in the -mm tree if you want, it makes it much simpler) > st also needs changes.

It really is a > single device requiring multiple dev entries. Create multiple class_device items for every tape device and have the device symlink point to the same scsi device. The simple_class code should make life a lot easier for you. > For scsi_id support with udev, st needs to support SG_IO, AFAIUI it can > use similiar code as found in sd.c and sr.c. That's a scsi core issue, not a udev issue :) thanks, greg k-h ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
