mempool_resize — resize an existing memory pool
int fsfuncmempool_resize ( | mempool_t * pool, |
| int new_min_nr, | |
gfp_t gfp_mask); |
pool
pointer to the memory pool which was allocated via
mempool_create.
new_min_nrthe new minimum number of elements guaranteed to be allocated for this pool.
gfp_maskthe 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.
