The manpage update is a good idea. I'm not sure about the MAINTAINERS
status - we do have 'Obsolete' but I'm reluctant to mark inotify as
obsolete as it's perfectly fine for existing users, we fully maintain it
and support it but we just don't want to extend the API anymore. Amir, what
are your thoughts on this?
