NAME¶
mempool_resize - resize an existing memory poolSYNOPSIS¶
int
mempool_resize(mempool_t * pool,
int new_min_nr,
gfp_t gfp_mask);
ARGUMENTS¶
poolpointer 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.COPYRIGHT¶
