# $FreeBSD$
#
# This list is semi-obsoleted by DEVFS, but for now it still contains
# the current allocation of device major numbers.
#
# Unless very special circumstants demand otherwise, all device drivers
# are able to use a dynamically allocated major number. If the d_maj
# element of the cdevsw is uninitialized (preferred) or initialized to
# MAJOR_AUTO, this dynamic allocation will happen.
#
# NOTICE: FreeBSD does not use block major numbers anymore, you neither
# need to assign nor use a block major number for any device driver any
# more.
#
# The names marked with a '*' is belived to be allocated for code inside
# the CVS tree.
