1) this is the same fscking thing we have now with ifdef __KERNEL__
Except it is completely ignored by the preprocessor.
2) if you are coming up with a -new- token, realize that
kernel-private stuff is the common case, and use
LIBC_KERNEL_SHARED_{BEGIN,END} instead
Sure, whatever works... the points I am trying to make are:
* Don't pollute kernel headers with unnecessary pre-processor junk.
* Give the LIBC people the power to choose which parts of the
headers they ingore and otherwise.
* Linus et al, can merge patches from LIBC people knowing they
should only affect LIBC, not the kernel.
It doesn't matter what the token(s) is/are --- by making them comments
and invisible to the kernel is make life easier.
Also, if the LIBC people want something like:
typedef unsigned int uint32_t;
then it could look like:
/* LIBC_ONLY_BEGIN
typedef unsigned int uint32_t;
LIBC_ONLY_END */
or whatever. All the libc specific stuff hidden in comments, and
shared stuff indictaed by comments. A simple script can then produce
LIBC suitable headers from the kernel ones.
