Andrii Nakryiko	7b3a063824	selftests/bpf: Test libbpf's ringbuf size fix up logic ... Make sure we always excercise libbpf's ringbuf map size adjustment logic by specifying non-zero size that's definitely not a page size multiple.

Yauheni Kaliuta	cfc0889ceb	selftests/bpf: ringbuf_multi: Test bpf_map__set_inner_map_fd ... Test map__set_inner_map_fd() interaction with map-in-map initialization. Use hashmap of maps just to make it different to existing array of maps.

Yauheni Kaliuta	f3f4c23e12	selftests/bpf: ringbuf_multi: Use runtime page size ... Set bpf table sizes dynamically according to the runtime page size value. Do not switch to ASSERT macros, keep CHECK, for consistency with the rest of the test. Can be a separate cleanup patch.

Andrii Nakryiko	cb1c9ddd55	selftests/bpf: Add BPF ringbuf selftests ... Both singleton BPF ringbuf and BPF ringbuf with map-in-map use cases are tested. Also reserve+submit/discards and output variants of API are validated.
