- int mempool_resize(mempool_t * pool, int new_min_nr, gfp_t gfp_mask);
- pointer to the memory pool which was allocated via mempool_create.
- the new minimum number of elements guaranteed to be allocated for this pool.
- the usual allocation bitmask.
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.
