[PATCH bpf-next v11 0/7] bpf-core changes for preparation of

[Benjamin Tissoires]

Hi,

well, given that the HID changes haven't moved a lot in the past
revisions and that I am cc-ing a bunch of people, I have dropped them
while we focus on the last 2 requirements in bpf-core changes.

I'll submit a HID targeted series when we get these in tree, which
would make things a lore more independent.

For reference, the whole reasons for these 2 main changes are at
https://lore.kernel.org/bpf/20220902132938.2409206-1-benjamin.tissoires@xxxxxxxxxx/

Compared to v10 (in addition of dropping the HID changes), I have
changed the selftests so we can test both light skeletons and libbbpf
calls.

Cheers,
Benjamin
