NAME
       mempool_create - create a memory pool

SYNOPSIS
       mempool_t * mempool_create(int min_nr, mempool_alloc_t * alloc_fn, mempool_free_t * free_fn, void * pool_data);

ARGUMENTS
       min_nr
	   the minimum number of elements guaranteed to be allocated for this pool.

       alloc_fn
	   user-defined element-allocation function.

       free_fn
	   user-defined element-freeing function.

       pool_data
	   optional private data available to the user-defined functions.

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.
