Yes, if cd63f3c is not included, so c1fa0768a871 is not necessary.

Yes, that's correct.

I don't know Canonical's plan exactly for 4.4. But if you confirm Xenial is based on 4.4
and it does not include cd63f3c, so we are fine and there is nothing to test on 4.4 based.

Is HWE 4.13 based affected? I see cd63f3c but not c1fa0768a871 in:

Ubuntu-hwe-4.13.0-42.47_16.04.1

but not sure if it's the right Ubuntu branch.

Thanks.
