That's a real shame, and very unlike Linus to advocate for just breaking
applications willy nilly. It would be a considerable amount of work
though, but it would really be great to not have ->read/->write anymore
and solely use the iter variants.
Not sure if I agree with "that bad" though looking at the number of
fixups, and we'll keep finding these going forward as well...
