> If you want to show the total number of available objects in both the common pool and the caches, you can calculate is as common_count + cache_count, instead of calling rte_mempool_avail_count(). And "total_count" would be a better name than "common_pool_avail_count".

No reply...
I assume it is a rejected patch.
