This feels to me like a new feature for arm64, one that has never worked
before and you are just making it feature-parity with x86, right?

Or is this a regression fix somewhere?  Why is this needed in 5.15.y and
why can't people who need this new feature just use a newer kernel
version (5.19?)

thanks,
