Agree Stephen. But rte_ring is not as basic as spinlock. IMO, existing note results in more questions than answers. From: Stephen Hemminger Sent: Tuesday, May 29, 2018 9:39 PM To: Honnappa Nagarahalli Cc: Olivier Matz ; dev@dpdk.org Subject: Re: [dpdk-dev] [PATCH] rte_ring: clarify preemptable

[dpdk-dev] [PATCH] rte_ring: clarify preemptable nature of ring algorithm
