>Description:

The filesystem module corresponding to mount_null(8) is installed
as "null.kmod", and therefore is loaded by "modload null"; but it
identifies itself as "nullfs", and therefore must be unloaded by
"modunload nullfs", not "modunload null".

>How-To-Repeat:

See above.  (Obviously this needs a kernel which is MODULAR and
also not MONOLITHIC.)

>Fix:

Someone should decide whether it's "null" or "nullfs" and change
the module filename resp. the module's internal name.
