Store them and ef_type in bit-fields. Allocate eight bits for ef_type. Values range from 0 to EF_GAME (currently 16), so this is plenty. Allocate twelve bits for sequence numbers. Sequence number mismatches are now missed when the numbers are equal modulo 2^12. Still sufficiently improbable. Common machines store the bit-fields in a 32 bit word. There are twelve bits left in that word for future use. Total savings 16 bits, which is exactly what the previous commit spent on wider uids on common machines.
