Sure, a follow-up cleanup is fine, but critically the cleanup need not be backported, which is why I said: | I completely agree the ifdeferry is ugly, and I do intend to follow up on | that regardless. If you feel strongly that we should get rid of that now, I | can spin a v2 with a second patch to clean that up; otherwise I'll do that as | part of a later series. Since Will has taken this patch as-is, and the fixes for v5.16-rc4 have already been tagged, I'll follow up with cleanup once that's merged to avoid being based on an ephemeral branch.
