CEPH KRBD Object-map fast-diff

So in the latest 5.3 Kernel object-map & fast-diff have been added : https://git.kernel.org/pub/scm/linu.../?id=d9b9c893048e9d308a833619f0866f1f52778cf5

This means we can get enhanced performance in certain operations and also means we can enable object-map on images and get real time reporting of true RBD size.

Obviously understand it's only just hit the 5.3 kernel but is this something Proxmox would be able to get added into the current 5.x kernel used? or would we need to wait for Ubuntu e.t.c to move to the 5.3.x stream?
Ubuntu Eoan (19.10) should be shipping the 5.3 kernel - and we plan on switching to that once it's released (and after enough testing) - so this will probably be the time the improvements become available

I hope this helps!
