4.procrank确定内核分配的地址空间，修改内核测试模块，增加分配4M内存的操作。
static int char_demo_open(struct inode *inode, struct file *file){
printk(KERN_EMERG "chardevnode_open is success!imajor %d, iminor %d.\n", imajor(inode), iminor(inode));
void *p = kmalloc(GFP_KERNEL, 4*1024*1024);
printk("%s lien %d, p = %p.\n", __func__, __LINE__, p);
return 0;
}我们先不安装测试模块，看只运行测试代码，看内存的使用情况，作为对照：
int main(int argc,char **argv)
{
int fd;
FILE *f;
char *char_demo_test_node0 = "/dev/char_demo_test0";
char *char_demo_test_node1 = "/dev/char_demo_test1";
#if 0
fd = open(char_demo_test_node0,O_RDWR|O_NONBLOCK);
if(fd < 0)
{
printf("%s open fail!!!\n",char_demo_test_node0);
exit(-1);
}
else
{
printf("%s open success !!!\n",char_demo_test_node0);
}
#endif
while(1)
{
sleep(1);
}
运行测试用例，然后在运行procrank.
之后,加载模块，修改用例，增加对设备节点的打开访问， 重新运行用户太用例：
确实打印了出来：
可以看到，调用了open后，内核4M内存成功分配了出来，此时运行procrank的结果是：
并没有明显变化。
这说明，通常所说的VSS，RSS，USS，PSS这些内存指标都是对用户态地址空间的度量，并不包括内核态分配的地址，这部分地址不会包括在VMA里面。
通过strace分析procrank的工作原理：
此功能依赖内核打开CONFIG_PROC_PAGE_MONITOR选项,否则,无法生成对应的/proc/PID/pagemap文件.

为了排除共享库干扰，我们使用手搓汇编的方式来验证一下：
section .data ;section declaration
msg db "Hello, world!",0xA ;our dear string
len equ $ - msg ;length of our dear string
section .text ;section declaration
;we must export the entry point to the ELF linker or
global _start ;loader. They conventionally recognize _start as their
;entry point. Use ld -e foo to override the default.
_start:
;write our string to stdout
mov eax,4 ;system call number (sys_write)
mov ebx,1 ;first argument: file handle (stdout)
mov ecx,msg ;second argument: pointer to message to write
mov edx,len ;third argument: message length
int 0x80 ;call kernel
;and exit
jmp _start
mov eax,1 ;system call number (sys_exit)
xor ebx,ebx ;first syscall argument: exit code
int 0x80 ;call kernel使用nasm编译，然后由ld链接：
czl@czl-VirtualBox:~/procrank$ nasm -f elf64 huibian.S
czl@czl-VirtualBox:~/procrank$ ld -s -o huibian ./huibian.o
czl@czl-VirtualBox:~/procrank$执行./huibian，会不断的打印 "helloworld"
查看它的memory map:
