MEMPOOL_RESIZE(9)                   Memory Management in Linux                  MEMPOOL_RESIZE(9)



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.
