Eventually, yes and in selftest/bpf.
But these examples depend on using security blobs and some non-atomic
calls in the BPF helpers which are not handled as a part of the
initial patch-set.
Once we have the initial framework finalized, I will update the
examples and the helpers they are based on and send these separate
patch-sets on the list for review.
