Can anyone tell me why the odd numbered MTD character devices are ReadOnly?

I see the code in MTDCHAR.C, but I have no idea what it was setup this way.


 /* You can't open the RO devices RW */
 if ((file->f_mode & 2) && (minor & 1))
  return -EACCES;

Thanks for any understanding you can provide...

Say "boolah boolah boolah" out loud three times,
wave a dead chicken, and reboot.
Works for me...
