Or we can just take c51c9cd8addc ("fs: dlm: don't put dlm_local_addrs on
heap") into the relevant trees?

Hi Sasha,
Just my 2c, but backporting c51c9cd8addc ("fs: dlm: don't put dlm_local_addrs on
heap") feels a bit riskier than just correcting the call to kernel_bind(), as it's a much
bigger change. Maybe someone more familiar with the dlm codebase can chime in
and say whether or not they are confident with backporting this change.
It's a bigger change, but in our experience it's the small fixups that
end up carrying the bigger risk.
Backporting the original change also has the advantage of preventing
similar issues from happening in the future.
