unsigned intnents
gfp_tgfp_mask
151  如果nents恒等于Maximum number of entries that will be allocated in one piece, if* a list larger than this is required then chaining will be utilized.则
161  ptr等于__get_free_page(gfp_mask)
162  kmemleak_alloc - register a newly allocated object*@ptr: pointer to beginning of the object*@size: size of the object*@min_count: minimum number of references to this object. If during memory* scanning a number of references less than @min_count is found,
163  返回:ptr
164  否则返回:分配数组内存
