  Yes, you'll get only "something has changed in a subtree" information for
each directory. You'd then have to rescan the directory to find out what
has changed. But there's no simple solution for this - either you have to
process tons of events for busy directory tree or you have to somehow
reduce the amount of information provided to userspace...
