[PATCH 1/8] mm: Add ptep_try_set() for lockless empty-slot installs

Hello, David.

Do you mean the comment cleanup I just sent, or the original
ptep_try_set() merge?

The original went through several rounds, and you acked the patch that
introduced both problems (258df8fce42f) before it landed.

The barriers fix came from Catalin, he raised the issue and reviewed the
fix. The comment cleanup got picked up quickly. Maybe that's the bpf
folks wanting it in ahead of the merge window.

Thanks.
