Would you mind explaining how you need to override this and why? I'm
afraid I did not quite get it from your description in the RFC (which is
also why I didn't come up with a solution either).
Am I correct that you need to return false if the passed in offset is
the cell header offset -8, or is there anything else at all required to
that logic? You mentioned something about the high order byte being
masked on AArch64, but didn't quite connect the dot to how that is
related to this code. Is it?
