A negative module use count (specifically "-1") depends on whether a module has a "can_unload" routine. If it does not have a "can_unload" routine, then chances are either the module decided "I can never be removed" or else the module is buggy.
However, if a "can_unload" routine does exist (as in ipv6) then the module use count is unconditionally set to "-1".
