[RFC PATCH bpf-next 07/12] selftests/bpf: exercise the path ancestor iterator

[sashiko-bot at kernel.org]

> Walk the ancestry of a mkdir's parent directory from a sleepable LSM
> program and check that the iteration reaches the root: the temporary
> directory, its parent and / are visited, and no position comes back
> flagged.
> 
> Resolve the second position's pathname from the acquired position after
> the step that yielded it has been taken, so that the acquired reference
> is what the sleepable kfunc runs on rather than the walk's.
