Let me spend some time on this. So, I guess this patch can't catch up with the merge window.
And I still have some patches that have not been picked, can you take a look, hope they can
catch up with the window.

How long is the 6.2 merge window left and when will you send the f2fs 6.2 pull request?

Thx,
Yangtao
