From d943c60565c04e1143acf36d6c2abca1152bd36d Mon Sep 17 00:00:00 2001 From: Feifei Wang Date: Sun, 20 Sep 2020 06:48:52 -0500 Subject: [PATCH] test/ring: fix dequeued object checks When using memcmp function to check data, the third param should be the size of all elements, rather than the number of the elements.
