Well, the packetdrill test was relying on old kernel behavior (not
very precise USER_TIMEOUT implementation),
and the test had comments explaining this (
https://github.com/google/packetdrill/commit/094da3bc77e518d820ebc0ef8b94a5b4cf707a39
So old packetdrill test only pass on old kernels.
Really the new packetdrill test is now checking the behavior of recent kernels
and making sure future kernels won't regress.
