override_release

函数名称：Work around broken programs that cannot handle "Linux 3.0".* Instead we map 3.x to 2.6.40+x, so e.g. 3.0 would be 2.6.40* And we map 4.x and later versions to 2.6.60+x, so 4.0/5.0/6.0/... would be* 2.6.60.

函数原型：static int override_release(char __user *release, size_t len)

返回类型：int

参数：

类型	参数	名称
char __user *	release
size_t	len

ret等于0

1217

如果personality按位与UNAME26则

1218

rest等于UTS_RELEASE

1219

char buf[65] = {0}
