Does this patch work with compressed images? Especially the
out-of-order write mode may be problematic with a compressed qcow2
image.
It does, but you are right, out-of-order writes and compression should
be mutually exclusive.
Sorry for being late, but can you please explain to me, why?
There are image format-specific limitations on compressed writes. For
some reason I thought they were append-only in qcow2, but I was wrong.
