Hi everyone,

Sorry for the delayed response -- I was traveling and didn’t have
access to email.

Thank you for the feedback. I realize I missed some key reviewers in
the CC list for this patch.
When I ran get_maintainer.pl, it returned a large list of recipients.
To avoid over-CC’ing people (which has been an issue for me in the
past), I tried to trim it down to maintainers and a few others I
thought would be interested. Clearly, I got it wrong and missed some
key folks. That was not my intention, and I’ll make sure to fix it
when I resend the patch as an RFC.

On the technical side, Liam is right that the copy-pasted arch code
has inconsistencies (missing checks, order of checks, ...). I agree
there’s room for further consolidation. I’ll take another stab at it
and resend it as an RFC with an updated cover letter, as Lorenzo and
others suggested.

Thanks,
Kalesh
