Would you prefer I start another version and include the key maintainers
from fs/exec.c, kernel/exit.c, and kernel/fork.c?

I've added akpm and brauner in these patches. I've pinged akpm privately
about these, but didn't get any responses.

It seems like Eric Biederman, Kees Cook, and linux-mm would be good
folks to add here from get_maintainers outputs.

Thoughts?

Thanks,
