I've actually never heard of --reflink, so I had to look it up. `cp` from coreutils uses the FICLONE ioctl to clone the file on btrfs instead of a regular syscall.
I don't handle them specifically in dut, so it will total up whatever statx(2) reports for any reflink files.
You’ll probably end up with dupes (and removing these files won’t have the effect you intend) but I don’t know that there’s a good way to handle and report such soft links anyway.
