3) Add capability for libbpf to resize datasec maps when backed via mmap, from JP Kobryn.
4) Move all the test kfuncs for CI out of the kernel and into bpf_testmod, from Jiri Olsa.
5) Big batch of xsk selftest improvements to prep for multi-buffer testing, from Magnus Karlsson.
6) Show the target_{obj,btf}_id in tracing link's fdinfo and dump it via bpftool, from Yafang Shao.
7) Various misc BPF selftest improvements to work with upcoming LLVM 17, from Yonghong Song.
8) Extend bpftool to specify netdevice for resolving XDP hints, from Larysa Zaremba.
