Subject: [dpdk-stable] [PATCH v4 4/7] test/ring: fix wrong number of enq/deq elements
Date: Mon, 14 Sep 2020 09:33:47 -0500
Message-ID: <20200914143350.18650-5-feifei.wang2@arm.com> (raw)
In-Reply-To: <20200914143350.18650-1-feifei.wang2@arm.com>

The ring capacity is (RING_SIZE - 1), thus only (RING_SIZE - 1) number of
elements can be enqueued into the ring.

Fixes: af75078fece3 ("first public release")
