Gaah. Yeah, I guess I could have done the trivial ugly merge that just
took the new copy_from_iter_flushcache() as-is, and didn't match it up
with all the new iov_iter hardening.

Except I decided I don't want that, and want to do a proper merge instead.

Which made the trivial merge something that actually changed that
copy_from_iter_flushcache() logic, and maybe I screwed it up in the

It builds, and it looks right to me, but you and Dan should really
check out the end result.

Particularly so for the CONFIG_ARCH_HAS_UACCESS_FLUSHCACHE logic,
which is where this differs from the other cases, and which I changed
to make the #ifdef less noticeable.

I did try both a i386 and a x86-64 build of the iov_iter code, since
that should test both of those ARCH_HAS cases, but that was purely a
build test.

Also, the new __must_check warnings do trigger. At least for lustre. I
couldn't be arsed to try to fix those, since .. lustre. But I'm also
adding a couple of lustre people to the cc, just to make them aware of
it.. I'd really like the allmodconfig build to be clean.
