the file I used:

#ifndef _TRANSPORT_RELAYFS_H_ /* -*- linux-c -*- */
#define _TRANSPORT_RELAYFS_H_
#define RELAYFS_VERSION_GE_4 

/** @file relayfs.h
 * @brief Header file for relayfs transport
 */

#ifdef RELAYFS_VERSION_GE_4
#include <linux/relayfs_fs.h>
#else
#include "../relayfs/linux/relayfs_fs.h"
#endif /* RELAYFS_VERSION_GE_4 */

struct rchan *_stp_relayfs_open(unsigned n_subbufs,
                                unsigned subbuf_size,
                                int pid,
                                struct dentry **outdir);
void _stp_relayfs_close(struct rchan *chan, struct dentry *dir);

#endif /* _TRANSPORT_RELAYFS_H_ */

So is it due to the gcc version? My gcc is:
gcc version 3.4.5 20051201 (Red Hat 3.4.5-2)
I checked the codes, and it is just a warning of the assignment:
int *ptr <--- static int *ptr

But I met another problem, I use my testcase to stress test systemtap:

-bash-3.00# ./test.sh -f  lgl.cfg  -I tapsets/tapsets1/           
The tapsets is tapsets/tapsets1/
don't probe app : dbench
TIMES : 1
TIMES : 2
probe app : dbench
TIMES : 1
TIMES : 2
error opening file stpd_cpu0.
ERROR: couldn't unlink percpu file stpd_cpu0: errcode = No such file or directory

Do you have any ideas of such errors? I never met it before.
I raise the MAXDSKIPPED when running my testcases
