Dear Greg,

Would you consider KASan for ARM patches for LTS (5.10) kernel? Those are 7a1be318f579..421015713b30 if I understand correctly. They are not normal stable material, but I think they will help tremendously in discovering kernel bugs on 32-bit ARMs.

Looks like a new feature to me, right?

How many patches, and have you tested them? If so, submit them as a patch series and we can review them, but if this is a new feature, it does not meet the stable kernel rules.

And why not just use 5.11 or newer for discovering kernel bugs? Why does 5.10 matter here?

thanks,
