Thanks for letting me know, strangely, it is here:
https://lkml.kernel.org/r/20251024-swap-clean-after-swap-table-p1-v2-1-c5b0e1092927@tencent.com

But the In-reply-to id is wrong. I'm using b4 and somehow patch 1 was
blocked by gmail's SMTP so I had to try to resend patch 1 again,
something went wrong with that part. I'll try to find out the problem
and avoid that from happening again.

I'm seeing that patch 1 is being merged into mm tree just fine, I
guess that should be OK.

If anyone is reading the threads, this url above should be helpful.
