[PATCH 0/3] Update LLVM Phabricator and Bugzilla links

[PATCH 0/3] Update LLVM Phabricator and Bugzilla links

[Nathan Chancellor]

This series updates all instances of LLVM Phabricator and Bugzilla links
to point to GitHub commits directly and LLVM's Bugzilla to GitHub issue
shortlinks respectively.

I split up the Phabricator patch into BPF selftests and the rest of the
kernel in case the BPF folks want to take it separately from the rest of
the series, there are obviously no dependency issues in that case. The
Bugzilla change was mechanical enough and should have no conflicts.

I am aiming this at Andrew and CC'ing other lists, in case maintainers
want to chime in, but I think this is pretty uncontroversial (famous
last words...).

[PATCH 1/3] selftests/bpf: Update LLVM Phabricator links

[Nathan Chancellor]

reviews.llvm.org was LLVM's Phabricator instances for code review. It
has been abandoned in favor of GitHub pull requests. While the majority
of links in the kernel sources still work because of the work Fangrui
has done turning the dynamic Phabricator instance into a static archive,
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.

Thanks a lot for catching this and providing an ack. Andrew, could you

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

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

https://lore.kernel.org/20240111-bpf-update-llvm-phabricator-links-v2-1-9a7ae976bd64@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

[PATCH 2/3] arch and include: Update LLVM Phabricator links

[Nathan Chancellor]

reviews.llvm.org was LLVM's Phabricator instances for code review. It
has been abandoned in favor of GitHub pull requests. While the majority
of links in the kernel sources still work because of the work Fangrui
has done turning the dynamic Phabricator instance into a static archive,
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.

[PATCH 3/3] treewide: Update LLVM Bugzilla links

[Nathan Chancellor]

LLVM moved their issue tracker from their own Bugzilla instance to
GitHub issues. While all of the links are still valid, they may not
necessarily show the most up to date information around the issues, as
all updates will occur on GitHub, not Bugzilla.

Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number. Thankfully, LLVM maintains this mapping
through two shortlinks:

  https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
  https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>

Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up
to date information. Each migrated issue links back to the Bugzilla
entry, so there should be no loss of fidelity of information here.
