Hmm... still don't understand what are you trying to fix. That reflink operation need long time, that's expected. The first time it's running in a while loop for getting a proper testing size, no matter 8.01s or 9s, I think it's all good. The second time the reflink run with `TIMEOUT_PROG 2s`, we expect it can be killed in 'timeout=8s', that's long enough. I think it's not necessary to care about it's keep running in 8.01s or 9s.
