From 708d904451c8f8e431cd783753812e1ffe7a92fc Mon Sep 17 00:00:00 2001 From: Feifei Wang Date: Sun, 28 Jun 2020 14:23:47 +0800 Subject: [PATCH] ring: fix tail in peek API for ST mode 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.
