[linux-lvm] lvm-vdo, snapshots and cache

Dear all,
as previous vdo utils are gone in RHEL9, VDO volumes must be created via 
lvm-vdo and associated lvm commands.

What is not clear to me is how to combine lvm-vdo with lvmthin (for fast 
CoW snapshots) and/or lvmcache (for SSD caching of an HDD pool). For 
example, with the old /dev/mapper/vdo style volumes (ie: the one created 
via vdo create) one can do something as physical_dev -> vdo -> lvmthin 
-> lvmcache.

How to do the same with lvm-vdo?
