But from your side what do we have?  Just direct NAKs without much

vaguely pointed to Linus's comments about it in the past, with no precise

strong enough to recommend using kernel types in user space, so I pushed v2,
and the discussion was kept.

So despite me saying that "this is not ok", and many other maintainers
saying "this is not ok", you applied a patch with our objections on it?
That is very odd and a bit rude.

I would like that if you still oppose to the patch, at least were able to
provide some facts to this discussion.

The fact is that the kernel can not use the namespace that userspace has
with ISO C names.  It's that simple as the ISO standard does NOT
describe the variable types for an ABI that can cross the user/kernel
boundry.

Work with the ISO C standard if you wish to document such type usage,
and get it approved and then we would be willing to consider such a
change.  But until then, we have to stick to our variable name types,
just like all other operating systems have to (we are not alone here.)

Please revert your change.
