inotify works fairly well if you have a small set of files or directories that you want to look for changes in, but it doesn't work if you want to find out about changes throughout the filesystem

We have leases in fcntl() F_SETLEASE, they go alongside dnotify in fcntl() F_NOTIFY.
inotify could similarly benefit from an an ilease extension, as well as further scalability improvements. (inotify was designed to improve on dnotify in many ways including scalability; it's a shame it stopped half way).
That's blocking readers right there.
