Very well, I've sent a standalone v2 on top of bpf-next:

https://lore.kernel.org/20240111-bpf-update-llvm-phabricator-links-v2-1-9a7ae976b...@kernel.org/

Andrew, just drop selftests-bpf-update-llvm-phabricator-links.patch
altogether in that case, the other two patches are fine to go via -mm I
think.

Cheers,
Nathan

Please send a new patch.
We'd like to take all bpf patches through the bpf tree to avoid conflicts.

reviews.llvm.org was LLVM's Phabricator instances for code review. It

there are some issues with that work, so preemptively convert all the
links in the kernel sources to point to the commit on GitHub.

Most of the commits have the corresponding differential review link in
the commit message itself so there should not be any loss of fidelity in
the relevant information.

Additionally, fix a typo in the xdpwall.c print ("LLMV" -> "LLVM") while
in the area.
