pcpu_get_pages

函数名称：pcpu_get_pages - get temp pages array* Returns pointer to array of pointers to struct page which can be indexed* with pcpu_page_idx(). Note that there is only one array and accesses* should be serialized by pcpu_alloc_mutex.* RETURNS:

函数原型：static struct page **pcpu_get_pages(void)

返回类型：struct page

参数：无

pages_size等于pcpu_nr_units乘pcpu_unit_pages乘pages[0]的长度

lockdep_assert_held( & pcpu_alloc_mutex)

如果非pages则pages等于pcpu_mem_zalloc - allocate memory*@size: bytes to allocate*@gfp: allocation flags* Allocate @size bytes. If @size is smaller than PAGE_SIZE,* kzalloc() is used; otherwise, the equivalent of vzalloc() is used.

返回:pages
