Thanks for your fix.

let's test previous commit to see if my really fixes this issue

#syz test: 
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git 
3bf7edc84a9eb4007dd9a0cb8878a7e1d5ec6a3b3bf7edc84a9eb4007dd9a0cb8878a7e1d5ec6a3b

Given the Reported-and-tested-by tag in syzbot's echo [1], can you try and
bisect the curing commit in your spare cycles?

Hm, that's odd. Last hit was 4d09h ago and I don't see related patches 

Wonder if you mean it was reproduced four days ago by "Last hit was 4d09h ago".

Yes, exactly.

If it was then can you share the splat? Anything different from the
syzbot report [2] on Tue, 22 Jun 2021?

IIRC syzbot tests on top of newest updates. I.e. last time syzbot 
reproduced this issue on top of v5.17-rc7 at least. So fix commit should 
somewhere between v5.17-rc7..HEAD
