sys/kern kern_conf.c kern_device.c
Log:
Because destroy_all_dev() checks the mask/match against the device's si_udev,
which is a field combining both major and minor numbers, we must mask off the
major bits (to retain only the minor bits) from the 'mask' variable in order
to allow a generic -1 to be passed as the mask. Otherwise we will not match
anything.
Revamp a good chunk of the documentation to try to make the major/minor
number masking issues clear.
