    3 # Major numbers are now assigned in RELENG_4.  This file is left to
    4 # rot in peace in 5.x/6.x.
    5 #
    6 # This list is semi-obsoleted by DEVFS, but for now it still contains
    7 # the current allocation of device major numbers.
    8 #
    9 # Unless very special circumstants demand otherwise, all device drivers
   10 # are able to use a dynamically allocated major number.  If the d_maj
   11 # element of the cdevsw is uninitialized (preferred) or initialized to
   12 # MAJOR_AUTO, this dynamic allocation will happen.
   13 # 
   14 # NOTICE: FreeBSD does not use block major numbers anymore, you neither
   15 # need to assign nor use a block major number for any device driver any
   16 # more.
   17 #
   18 # The names marked with a '*' is belived to be allocated for code inside
   19 # the CVS tree.
