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.
60  * NCHUNKS_ORDER determines the internal allocation granularity, effectively
63  * allocation granularity will be in chunks of size PAGE_SIZE/64. As one chunk
143 /* Converts an allocation size in bytes to size in zbud chunks */
181 	 * Add CHUNK_SIZE to the handle if it is the first allocation to jump  in encode_handle()
217  * Return: pointer to the new zbud pool or NULL if the metadata allocation
252  * @size:	size in bytes of the desired allocation
254  * @handle:	handle of the new allocation
257  * satisfy the allocation request.  A search of the unbuddied lists is
334  * zbud_free() - frees the allocation associated with the given handle
335  * @pool:	pool in which the allocation resided
336  * @handle:	handle associated with the allocation returned by zbud_alloc()
338  * In the case that the zbud page in which the allocation resides is under
486  * zbud_map() - maps the allocation associated with the given handle
487  * @pool:	pool in which the allocation resides
488  * @handle:	handle associated with the allocation to be mapped
491  * implementing this allocation API could have more complex information encoded
495  * Returns: a pointer to the mapped allocation
503  * zbud_unmap() - maps the allocation associated with the given handle
504  * @pool:	pool in which the allocation resides
505  * @handle:	handle associated with the allocation to be unmapped
