Hm, I guess nothing.  I was under the impression that the 'j' was the
"kernel number" there...  I guess I'll go delete that comment, sorry...

[udev] build_kernel_number() whats wrong with sdaj?

[Kay Sievers]

Hi Greg,
in namedev.c is:
/* FIXME, figure out how to handle stuff like sdaj which will not work right now. */
in TODO is:
fix kernel name logic to handle devices like sdaj and such

What exactly is the problem with sdaj?

I've made 50 pseudo scsi-adapter and put two partitions on sdaj and udev made:
  brw-------    1 root     root      66,  48 Dec 18 03:54 /udev/sdaj
  brw-------    1 root     root      66,  49 Dec 18 03:56 /udev/sdaj1
  brw-------    1 root     root      66,  50 Dec 18 03:56 /udev/sdaj2

in sd.c in the kernel is:
  if (index >= 26) {
  	sprintf(gd->disk_name, "sd%c%c", 'a' + index/26-1,'a' + index % 26);
  } else {
  	sprintf(gd->disk_name, "sd%c", 'a' + index % 26);
  }


thanks,
Kay
