From 71cfce73f454fcdd5b4e8e9629cd6f41900cef13 Mon Sep 17 00:00:00 2001 From: Mao Zhongyi Date: Wed, 3 Jun 2020 16:08:57 +0800 Subject: [PATCH] tests/migration: fix unreachable path in stress test If stressone() or stress() exits it's because of a failure because the test runs forever otherwise, so change stressone and stress type to void to make the exit_failure() as the exit function of main().
