Yes, sdf@ quoted the wrong sha1, it's a clean cherrypick to an
internal branch of
'bpf: Add cgroup helpers bpf_{get,set}_retval to get/set syscall return value'
commit b44123b4a3dcad4664d3a0f72c011ffd4c9c4d93.

Anyway, I think it's unrelated - or at least not the immediate root cause.
Also there's *no* Android kernels involved here.
This is the android net tests failing on vanilla 5.18 and passing on 5.18.3.
