Much lighter update this time around, as expected.
+ As of coreutils-8.32-11.fc33 the 'cp' command defaults to
reflink=auto, instead of reflink=never; this is consistent with
upstream master. This isn't exclusively a Btrfs change, XFS benefits
+ libvirt 6.6.0 storage pool code now attempts to disable COW by
default on btrfs; it can be disable (previously reported as patches
having landed, now it's merged)
