And for above "return rte_mp;" case, it skips "if (verbose_level > 0)" checks because of an early return. So what do you think remove above "return rte_mp;", and move here, instead of NULL return? <...> > @@ -264,6 +264,8 @@ extern struct fwd_engine ieee1588_fwd_engine; > > extern struct fwd_engine * fwd_engines[]; /**< NULL terminated array. */ > > +extern struct rte_mempool *mempools[RTE_MAX_NUMA_NODES]; There is no other .c file using 'mempools', can drop the extern.
