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.
