dnotify needed?

I have recently stumbled upon the "fs.dir-notify-enable" sysctl, which controls whether dnotify should be enabled, as inotify is the better one.  the question is, how can I know if I need that?  just running readelf -s on all applications and libraries and grepping the output isn't an option, as dnotify works through fcntl, so it doesn't have a symbol for itself...

Being the adventurous soul I am, I have disabled it.  but there may be some application that falls back to polling/busy-waiting, which is worse of-course.

What applications do you know that need dnotify?

Thanks.
