I would leave the allocation succeed and print warning that the debug
information is invalid. You could have a “dirty” flag which is set if
that happens (or on a partial release discussed earlier) which, if set,
would add “Some debug information missing” message at the beginning of
the procfs file. In my opinion CMA succeeding is more important than
having correct debug information.
