don't be sorry.
I'm glad that you spotted this ;)

I'm always confused about this and try to get the closest one, although
I prefer the linux style u32.

I went to
https://www.kernel.org/doc/html/v4.10/process/coding-style.html

"""
d. New types which are identical to standard C99 types, in certain
exceptional circumstances.

Although it would only take a short amount of time for the eyes and
brain to become accustomed to the standard types like uint32_t, some
people object to their use anyway.

Therefore, the Linux-specific u8/u16/u32/u64 types and their signed
equivalents which are identical to standard types are permitted –
although they are not mandatory in new code of your own.

When editing existing code which already uses one or the other set of
types, you should conform to the existing choices in that code.

I wonder if we should do a one time replace in all our code and start
accepting only one to avoid confusion.
