Hi. This fails to compile with clang:

  CC      qemu-seccomp.o
qemu-seccomp.c:112:1: error: unused function 'qemu_seccomp'
[-Werror,-Wunused-function]
qemu_seccomp(unsigned int operation, unsigned int flags, void *args)
^

This is because clang is stricter about warning about static inline
functions defined in .c files but never used and your ifdef
guard on the callsite is not matched by one around the function
definition.

thanks

Peter, sorry for not catching that before.
Marc, can you fix and resend?

I suggest to drop that patch from 3.0. Since it will require a newer
libseccomp to be actually useful, it can be delayed imho.
