__check_object

函数名称：Validates that the given object is:* - not bogus address* - fully contained by stack (or stack frame, when available)* - fully within SLAB object (or object whitelist area, when available)* - not in kernel text

函数原型：void __check_object_size(const void *ptr, unsigned long n, bool to_user)

返回类型：void

参数：

类型	参数	名称
const void *	ptr
unsigned long	n
bool	to_user

如果static_branch_unlikely( & bypass_usercopy_checks)则返回

如果非n则返回
