> Subject: [PATCH] eal: allow worker lcore stacks to be allocated from hugepage memory
>
> Add support for using hugepages for worker lcore stack memory. The
> intent is to improve performance by reducing stack memory related TLB
> misses and also by using memory local to the NUMA node of each lcore.
>
> EAL option '--huge-worker-stack [stack-size-kbytes]' is added to allow
> the feature to be enabled at runtime. If the size is not specified,
> the system pthread stack size will be used.

Should we also to check "worker_stack_size *1024 < PTHREAD_STACK_MIN" ?
