Looks good. Do you really want it all in a .h file? I don't mind
having the selinux functions being in a .c file and building that if
USE_SELINUX is enabled.
But it's your call, as you are the one going to have to live with the
code :)

Yeah, but logging.h has such tiny functions :)
Anyway, it's your decision.

Ok, feel free to send me a patch when you feel it should be applied.

Logic is backwards here.

This define is unncessary. Just call the function
do_add_selinux_stuff(), and protype it.
Actually, inline functions that do nothing if selinux is disabled is
better to catch compiler errors with types if things change in the
future.

perhaps the style should be that the Makefile adds some code
add_selinux.c based on a configure-time option,
and that some #ifdefs in a header file call a function which
is a stub in the header if WITH_SELINUX is not defined.
bizarre_but_likely_quite_good_coding_style_never_encountered_before.h:
#ifdef WITH_SELINUX
int do_add_selinux_stuff(args) { return 0; }
#else
#define do_add_selinux_stuff the_real_add_selinux_stuff
#endif
and add_selinux.c contains:
int the_real_add_selinux_stuff(args)
{
....
return err;
}

Truth, honesty and respect are rare commodities that all spring from
the same well: Love. If you love yourself and everyone and everything
around you, funnily and coincidentally enough, life gets a lot better.

Further cleanup and using all static inlines versus defines. Renamed a
couple of functions to make them clearer.
