I don't think it's a good idea to export that much detailed information.
That would become a stable ABI, but might not be possible to keep
all these details stable. e.g. map count or reference count are
internal implementation details that shouldn't be exposed.
And what is an user space application to do with the inode? Run
find -inum?

Also we already report the event using low level logging mechanism.
in a relatively stable form.

It's also unclear to me what an application would do with that much

I would suggest to drop this part and the earlier flags move.

Please only bug fixes are this stage.
