No, it's not.

You *should not* have links to those directories in your kernel
source.  There's a whole thread on this topic in debian-powerpc
from back in January of 2000 -- search for ``Subject: Continuing
annoyances...'' or ``Message-id:
<E125t1w-0000Jv-00@puetz.penguinpowered.com>'' in the archive.


Basically, though, Linus has made it pretty clear that you
shouldn't be including any header files from the kernel sources --
you should use the header files provided with libc (the header
files in /usr/include/linux come from the libc6-dev package), or
copy them into your source tree.  Using the kernel header files
directly can cause major breakage when you upgrade your kernel.

(As a point of interest, I recently had to copy a header file
(openpic.h) *from* /usr/include/linux back into the kernel tree,
because someone had taken out some symbols that the kernel needed.
They're back now.)
