mempool_resize: resize an existing memory pool

NAME

mempool_resize - resize an existing memory pool

SYNOPSIS

int mempool_resize(mempool_t pool, int new_min_nr);

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.

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. This function may sleep.

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.
