From 1c324bf908e3de1cf352e36484c73dc07767d938 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 17 Oct 2022 21:20:23 +0800 Subject: [PATCH] tests/qtest: vhost-user-test: Fix [-Werror=format-overflow=] build warning When tmpfs is NULL, a build warning is seen with GCC 9.3.0. It's strange that GCC 11.2.0 on Ubuntu 22.04 does not catch this, neither did the QEMU CI. While we are here, improve the error message as well.
