3-1：使用LInx专有的reboot系统调用重启系统时，必须将第二个参数magic2定义为一组magic号（例如：LINNUX_REBOOT_MAGIC2）。这些号有何意义？(将magic号转换为十六进制数，对解题会有所帮助。)
参考：Linux Easter Egg - Hidden Dates in the Linux Kernel
具体如下：
In order to prevent the reboot() system call being
called inadvertently, you must pass it a pair of magic values in the first two parameters. The first magic value is 0xfee1dead. The second magic value
is one of:
$ grep LINUX_REBOOT_MAGIC include/linux/*.h
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC1 0xfee1dead
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2 672274793
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2A 85072278
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2B 369367448
include/linux/reboot.h:#define LINUX_REBOOT_MAGIC2C 537993216
Here are the answers.
0xfee1dead ="Feel Dead"
672274793=0x28121969 28/12/1969 is when Linus Torvalds was born.
These are Linus' daughters' birthdays:
85072278= 0x5121996 05/12/1996 is when Patricia Miranda was born.
367369448=0x16041998 16/04/1998 is when Daniela Yolanda was born.
537993216=0x20122000 20/12/2000 is when Celeste Amanda was born
从中不难感受到Linus Torvalds对女儿们满满的爱啊！
