unsigned long zs_malloc	(	struct zs_pool *	pool,
		size_t	size
	)

zs_malloc - Allocate block of given size from pool. : pool to allocate from : size of block to allocate

On success, handle to the allocated object is returned, otherwise 0. Allocation requests with size > ZS_MAX_ALLOC_SIZE will fail.

void* zs_map_object	(	struct zs_pool *	pool,
		unsigned long	handle,
		enum zs_mapmode	mm
	)

zs_map_object - get address of allocated object from handle. : pool from which the object was allocated : handle returned from zs_malloc

Before using an object allocated from zs_malloc, it must be mapped using this function. When done with the object, it must be unmapped using zs_unmap_object.

Only one object can be mapped per cpu at a time. There is no protection against nested mappings.

This function returns with preemption and page faults disabled.
