函数名称:alloc_pages_exact - allocate an exact number physically-contiguous pages.*@size: the number of bytes to allocate*@gfp_mask: GFP flags for the allocation, must not contain __GFP_COMP* This function is similar to alloc_pages(), except that it allocates the
函数原型:void *alloc_pages_exact(size_t size, gfp_t gfp_mask)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
size_t | size | |
gfp_t | gfp_mask |
4953 | order等于get_order - Determine the allocation order of a memory size*@size: The size for which to get the order* Determine the allocation order of a particular sized block of memory |
4956 | 如果WARN_ON_ONCE(gfp_mask & __GFP_COMP)则gfp_mask与等于__GFP_COMP的反 |
4959 | addr等于Common helper functions. Never use with __GFP_HIGHMEM because the returned* address cannot represent highmem pages. Use alloc_pages and then kmap if* you need to access high mem. |
4960 | 返回:make_alloc_exact(addr, order, size) |
