[PATCH bpf-next v1 06/11] 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, no position comes back
> flagged, and the flags read back after the loop show it ended at the
> root rather than on a failed allocation.
> 
> Hold the first position across the rest of the walk and resolve its
> pathname only once the loop is done and the iterator destroyed: the
> acquired reference, not the walk's, is then all that keeps the
> position alive.
>
