Bug#850884: overlayfs does not implement inotify interfaces correctly

Hi,

this is still an issue on current kernels.

I am running Debian Live CD with 4.18.10, and tail -f, uses pooling on root
overlayfs, instead of inotify (verified using strace).

It is not a huge issue for tail itself, but for some other apps it can.

Thanks.
