AFAICT your fixes were archived before any reviewer had a chance to
take a look (perhaps due to LPC / Maintainer Summit). Could you repost,
and when you do drop the whitespace cleanups from this patch? There
should be no whitespace cleanups in fixes..

Have you written a test to exercise these code paths by any chance?
Adding one would be great.
