MEMPOOL_RESIZE(9)					    Memory Management in Linux						 MEMPOOL_RESIZE(9)

NAME
       mempool_resize - resize an existing memory pool

SYNOPSIS
       int mempool_resize(mempool_t * pool, int new_min_nr, gfp_t gfp_mask);

ARGUMENTS
       pool
	   pointer to the memory pool which was allocated via mempool_create.

       new_min_nr
	   the new minimum number of elements guaranteed to be allocated for this pool.

       gfp_mask
	   the usual allocation bitmask.

DESCRIPTION
       This function shrinks/grows the pool. In the case of growing, it cannot be guaranteed that the pool will be grown to the new size
       immediately, but new mempool_free calls will refill it.

       Note, the caller must guarantee that no mempool_destroy is called while this function is running.  mempool_alloc & mempool_free might be
       called (eg. from IRQ contexts) while this function executes.
