This is quite incorrect. Inheritance is only possible when a match of the
previous rule has succeeded. If a rule never applies in a given file, the
rules that inherit from it won't apply either. Furthermore, what is
inherited is the value, not the constraint. If the original binding of
alloc only ever matches kmalloc, then the inherited references will only
match kmalloc too.
