Subject: [dpdk-stable] [PATCH] ring: fix error vlaue of tail in the peek API for ST mode
Date: Sun, 28 Jun 2020 14:23:47 +0800 [thread overview]
Message-ID: <20200628062348.23063-1-feifei.wang2@arm.com> (raw)
The value of *tail should be the prod->tail not prod->head. After
modification, it can record 'tail' so head/tail can be updated
accordingly.
Fixes: 664ff4b1729b ("ring: introduce peek style API")
