kernel2.6.36 使用lsm问题

forlinux0518

RT

我在模块里
static int lsm_test_inode_symlink(struct inode *dir, struct dentry *dentry, const char *old_name)
{
return 0;
}
static struct security_operations lsm_test_security_ops = {
    .name =                         "os_sec",
    //.inode_symlink = lsm_test_inode_symlink,
};

et=register_security(&lsm_test_security_ops)；
出现如下错误
