Lines Matching full:allocation

38  * allocation function, zbud_alloc(), returns an opaque handle to the user,
41  * allocation data and unmap the handle with zbud_unmap() when operations
42  * on the allocation data are complete.
61  * NCHUNKS_ORDER determines the internal allocation granularity, effectively
64  * allocation granularity will be in chunks of size PAGE_SIZE/64. As one chunk
229 /* Converts an allocation size in bytes to size in zbud chunks */
267 	 * Add CHUNK_SIZE to the handle if it is the first allocation to jump  in encode_handle()
303  * Return: pointer to the new zbud pool or NULL if the metadata allocation
338  * @size:	size in bytes of the desired allocation
340  * @handle:	handle of the new allocation
343  * satisfy the allocation request.  A search of the unbuddied lists is
420  * zbud_free() - frees the allocation associated with the given handle
421  * @pool:	pool in which the allocation resided
422  * @handle:	handle associated with the allocation returned by zbud_alloc()
424  * In the case that the zbud page in which the allocation resides is under
572  * zbud_map() - maps the allocation associated with the given handle
573  * @pool:	pool in which the allocation resides
574  * @handle:	handle associated with the allocation to be mapped
577  * implementing this allocation API could have more complex information encoded
581  * Returns: a pointer to the mapped allocation
589  * zbud_unmap() - maps the allocation associated with the given handle
590  * @pool:	pool in which the allocation resides
591  * @handle:	handle associated with the allocation to be unmapped
