I don't believe it is.
But I won't pursue this further without patches.
I tried. It doesn't.
To be precise: directory changes like file creation (even creation of a file
that already exists) get notified, but purely file-based event like modifying
the contents of the file don't generate events back to the overlayfs
Because an open (for write) of a file is passed through to the upper
filesystem, the notifications of modification through that open only go to the
