Why the existing tests (without this patch) didn't fail? There could be two reasons: 1) "backlog" specifies the number of pending connections. As long as the server accepts the connections faster than the clients side connecting, connection will succeed. For the preempt test, it uses only 2 channels, so very likely to not have pending connections. 2) per my tests (on kernel 6.2), the number of pending connections allowed is actually "backlog + 1", which is 2 in this case. That said, the implementation of socket_start_incoming_migration_internal expects "migrate defer" to be used, and for safety, change the test to work with the expected usage.
