Thank you for your clarification.
Also, many thanks for maintaining the file-reflink storage driver.

[qubes-users] Btrfs (file-reflink): Why is the CoW on a volatile.img enabled?

[449f09c92]

I have /dev/xvdc configured as a 10GB swap and had to edit the relevant 
code to disable CoW when volatile.img is created to avoid overloading 
dom0 by checksum calculation when swapping out occurs in the VM.


Is there any reason why copy-on-write is enabled on volatile volumes 
that are mostly used as swap? Just curious.
