我的HTC Sensation XL有一个Android LKM，如下所示，它将在调用sys_open之前打印一条调试消息。我的操作系统是Ubuntu 11.10 64bit。 Android内核是从http://www.htcdev.com/devcenter/downloads下载的runnymede-crc-2.6.35。

  *系统调用sys_open dubugging

#include <linux/kernel.h>
  #include <linux/module.h>
  #include <asm/unistd.h>

asmlinkage ssize_t (*orig_open)(const char *pathname, int flags);

asmlinkage ssize_t hooked_open(const char *pathname, int flags)
  {
  printk(KERN_INFO "SYS_OPEN: %s\n", pathname);
  return orig_open(pathname, flags);
  }

static int __init root_start(void)
  {
  unsigned long sys_addr = 0xc003b104; /* System.map */
  unsigned long *sys_call_table= (unsigned long *)sys_addr;

orig_open = sys_call_table[__NR_open];
  sys_call_table[__NR_open] = hooked_open;
  return 0;
  }

static void __exit root_stop(void)
  {

unsigned long sys_addr = 0xc003b104;
  unsigned long *sys_call_table= (unsigned long *)sys_addr;

sys_call_table[__NR_open] = &orig_open;
  }

module_init(root_start);
  module_exit(root_stop);

但它在编译期间显示错误，

任何人都可以帮助我？
