You also need it in 5.19.y, right?  And you never want someone to
upgrade from an older kernel to a newer one and have a regression.

This commit does not cleanly cherry-pick, I need a working backport in
order to apply it.  As I'm sure you already have a working and tested
backport of it (otherwise you wouldn't have asked for it), can you
please send it to us so that it can be applied?

Same for 5.19.y too.

thanks,
