I think KCMP_FILE has to be used here ^^^^, because we compare files. We
have to use the same function for all files to be able to sort them, don't we?
Yes. I already have v2 in my queue. Strictly speaking we can use separate
salt here but it will be waste of memory from userspace POV. I didn't send
v2 yet since I'm modifying criu still to test overall picture. Hopefully
will send today.
