And now as qemu_file_rate_limit() never return negative value, what's
the
meaning for the check: if (qemu_file_rate_limit(f) < 0) in
ram_save_iterate()?
I only see a "while ((ret = qemu_file_rate_limit(f)) == 0)", no
less-than-zero check.
Are we looking at the same code? :)
I think so, hehe.
You might want to look a little more. After the while(..), there is a
check:
if (ret < 0) {
bytes_transferred += total_sent;
return ret;
}
Aha, there you are. It's dead code, you can delete it.
