Looks good.
I applied it, but then reverted since test_verifier needs to be adjusted:
./test_verifier 349
#349/p valid 1,2,4,8-byte reads from bpf_sk_lookup FAIL: Unexpected
bpf_prog_test_run error (Invalid argument) (run 1/1)

That's the only test that has ACCEPT for sk_lookup prog type
and the framework now is trying to run it.
Pls respin.
