mempool_resize - resize an existing memory pool
2. SYNOPSIS ▲
int mempool_resize(mempool_t * pool , int new_min_nr , gfp_t gfp_mask );
3. ARGUMENTS ▲
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.
4. 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.
