Name: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
Proto:void *alloc_pages_exact(size_t size, gfp_t gfp_mask)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
size_t | size | |
gfp_t | gfp_mask |
4953 | order = 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 | If WARN_ON_ONCE(gfp_mask & __GFP_COMP) Then gfp_mask &= ~__GFP_COMP |
4959 | addr = 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 | Return make_alloc_exact(addr, order, size) |

alloc_large_system_hash | allocate a large system hash table from bootmem* - it is assumed that the hash table must contain an exact power-of-2* quantity of entries* - limit is the number of hash buckets, not the total allocation size |
