Can you please provide steps to verify this fix - as we will blackbox test from the UI?

Michael - I'm running into issues finding a device that actually has fanotify enabled. So far, testing unagi and inari have shown that fanotify is not enabled. What devices is fanotify enabled on?

The official builds from tef/leo vendors will have it.

One way to check it is to look for the string "Warning: No fanotify support in this device's kernel." in logcat. If you find it, the device has no fanotify support.
