Description Nicolas Joly 2008-12-10 09:44:18 EST
Description of problem:
A C source code which include `/usr/include/linux/futex.h' header cannot compile anymore. This file has some kernel only definitions which are not correctly protected with __KERNEL__ #ifdef/#endif.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create C testcase file ...
[njoly@xx]~% cat >xx.c <<EOF
#include <linux/futex.h>
int main() { return 0; }
2. Try to compile it ...
[njoly@xx]~% cc xx.c   
Actual results:
In file included from xx.c:1:
/usr/include/linux/futex.h:96: error: expected ')' before '*' token
/usr/include/linux/futex.h:100: error: expected ')' before '*' token

Expected results:
No error.
