min_nr, mempool_alloc_t * alloc_fn, mempool_free_t* free_fn, void* pool_data);
Arguments
min_nr

Description
this function creates and allocates a guaranteed size, preallocated memory pool. The pool can be used from the mempool_alloc and mempool_free functions. This function might sleep. Both the alloc_fn and the free_fn functions might sleep – as long as the mempool_alloc function is not called from IRQ contexts.
