First I grabbed it from email, and I get the usual =3D (instead of =)
and =20 instead of a space. Longer lines also broken up, with an = at
the end.

Then I grabbed it from the lore io-uring archive, but it was the exact
same thing.

As per other email, I think you're having some coordination issues
with the reaping and submitting side being separated. If the reaper
isn't keeping up, you'll get the -EBUSY problem I saw. I'm assuming
that's the failure case you are also seeing, you didn't actually
mention how it fails for you?
