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.

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.
