I would like to participate in the discussion too.
The dm-clone target would also benefit from copy offload, as it heavily
employs dm-kcopyd. I have been exploring redesigning kcopyd in order to
achieve increased IOPS in dm-clone and dm-snapshot for small copies over
NVMe devices, but copy offload sounds even more promising, especially
for larger copies happening in the background (as is the case with
dm-clone's background hydration).
Thanks,

If you can document your findings here it will be great for me to
add it to the agenda.
Hi,
Give me a few days to gather my notes, because it's been a while since
the last time I worked on this, and I will come back with a summary of
my findings.
