I'm trying to let the code running on a RTOS, it seems I got quite a few 
KERNEL(_KERNEL, _KERNEL_) conflicts, anybody can give me a hand?

just for example, at fil.c, what's the usage of KERNEL here:
A: ****************************************************************
#ifndef	_KERNEL
# include "ipf.h"
# include "ipt.h"
extern	int	opts;
# define	FR_VERBOSE(verb_pr)			verbose verb_pr
# define	FR_DEBUG(verb_pr)			debug verb_pr
# define	IPLLOG(a, c, d, e)		ipllog()
#else /* #ifndef _KERNEL */
# define	FR_VERBOSE(verb_pr)
# define	FR_DEBUG(verb_pr)
# define	IPLLOG(a, c, d, e)		ipflog(a, c, d, e)
# define	FR_NEWAUTH(m, fi, ip, qif)	fr_newauth((mb_t *)m, fi, ip)
#endif /* _KERNEL */

B:*******************************************************************
void	fr_makefrip(hlen, ip, fin)
int hlen;
ip_t *ip;
fr_info_t *fin;
{
	u_short optmsk = 0, secmsk = 0, auth = 0;
	int i, mv, ol, off, p, plen, v;
	fr_ip_t *fi = &fin->fin_fi;
	struct optlist *op;
	u_char *s, opt;
	tcphdr_t *tcp;

	fin->fin_rev = 0;
	fin->fin_fr = NULL;
	fin->fin_tcpf = 0;
	fin->fin_data[0] = 0;
	fin->fin_data[1] = 0;
	fin->fin_rule = -1;
	fin->fin_group = -1;
#ifdef	_KERNEL
	fin->fin_icode = ipl_unreach;
#endif
	v = fin->fin_v;
	fi->fi_v = v;

C:********************************************************************
static	int	frflushlist __P((int, minor_t, int *, frentry_t **));
#ifdef	_KERNEL
static	void	frsynclist __P((frentry_t *));
#endif

thanks in advance!
