Sorry, I've completely missed this. I wasn't on CC and assumed
that was some sort of a repost. Going through the changes right now.
Hmmm, or maybe I shouldn't? This seems to be bases on some other tree;
can't find tools/testing/selftests/hid/Makefile (from patch #2) in neither
bpf nor bpf-next.
Alexei/Daniel/Andrii, what's the process with these series?
One question here: is it worth it extending bpf/vmtest.sh instead
to support boot2container? Why new script with a bunch of copy-paste
is a better deal?
