Actually, it says, "All of this makes very little difference to the
end-user, as they won’t see any specific changes."  (I'd probably add
the caveat that this assumes the end-user isn't compiling software
that uses linux headers.)

These are just C header files.  They expect optimizing them to
increase compiler performance (I imagine especially on smaller files),
which makes sense.  When the compiler has to read 10k lines of
includes that takes time even if they do nothing, and if you have 10
levels of typedefs or whatever nested that of course is work for the

In the end though the actual data types of variables probably aren't
going to change as a result of this.

Since many of these headers are used by userspace and the system call
interface they can't change the actual data types.  They're only
changing how they're expressed in the headers.  Obviously they need to
do it in a way that doesn't impact every C program that includes
something from linux-headers.
