From ca1ef1e62e581f61c40f8be49d222007739691c4 Mon Sep 17 00:00:00 2001 From: Andrey Shinkevich Date: Mon, 29 Jul 2019 15:46:00 +0300 Subject: [PATCH] tests: Set read-zeroes on for null-co driver This patch is to reduce the number of Valgrind report messages about using uninitialized memory with the null-co driver. It helps to filter real memory issues and is the same work done for the iotests with the commit ID a6862418fec4072.
