This was the latest mm-unstable as of 8/18/2024:

commit 8c0b4f7b65fd1ca7af01267f491e815a40d77444
Author: Zhaoyang Huang <zhaoyang.huang@...soc.com>
Date:   Thu May 11 13:22:30 2023 +0800

    mm: optimization on page allocation when CMA enabled

Let me rebase to the latest mm-unstable and send out an updated patchset.

mm-unstable as of 8/27/2024:

- Has some of Chris Li's patches to improve swap slot allocation:

https://patchwork.kernel.org/project/linux-mm/patch/20240730-swap-allocator-v5-3-cb9c148b9297@kernel.org/
https://patchwork.kernel.org/project/linux-mm/patch/20240730-swap-allocator-v5-2-cb9c148b9297@kernel.org/
https://patchwork.kernel.org/project/linux-mm/patch/20240730-swap-allocator-v5-1-cb9c148b9297@kernel.org/

- Does not yet have mTHP swapin as far as I can tell.

Thanks,
Kanchana
