Appologies for radio silence; As Catalin and I both said before, the arm email
servers drop all mail from Xavier <xavier_qy@....com> on the floor. I'm not sure
why, but any chance you could use a different email account to make this smoother?
I'm doing some testing of this now and will respond properly in the next few
days. But I don't personally like the complexity of the patch and am not totally
clear on if this is likely to show a real benefit in real-world use cases (as I
commented previously).
I'll respond properly once I have some results.
Given this is only touching arm64, I'd really prefer that this go via arm64 if
at all.
Thanks,
Ryan
