FWIW, yes, it is enough for primary sorting key. Once it matches the key from other anon block we use kcmp call to find exact match (kid_epoll_lookup lookups over primary keys generated by inode/sdev/pos, and then using kcmp we walk over files) https://github.com/cyrillos/criu/blob/epoll-tgt-3/criu/kcmp-ids.c#L158 Cyrill
