One question if you don't mind: if something similar came up again and
a test *was* warranted, which existing script would be the natural
home? mptcp_join.sh seemed closest since it exercises the accept path,
but i'm not sure if checking /proc/slabinfo fits there or if there's a
better mechanism for that kind of thing.

It depends on what needs to be covered:

- diag.sh: check various counters
- mptcp_connect.sh: single path
- mptcp_join.sh: multiple paths
- mptcp_sockopt.sh: socket options
- pm_netlink.sh: in-kernel path-manager
- simult_flows.sh: small multiple paths perf tests
- userspace_pm.sh : userspace path-manager
- + kunit: token and crypto
- + packetdrill: various tests

So not mptcp_join.sh. Maybe diag.sh, or in packetdrill.

Cheers,
Matt
