From 1b11063d32d7e11366e48be64215ff517ce32217 Mon Sep 17 00:00:00 2001 From: Daniel Latypov Date: Fri, 13 May 2022 11:37:07 -0700 Subject: kunit: fix executor OOM error handling logic on non-UML The existing logic happens to work fine on UML, but is not correct when running on other arches. 1. We didn't initialize `int err`, and kunit_filter_suites() doesn't explicitly set it to 0 on success. So we had false "failures". Note: it doesn't happen on UML, causing this to get overlooked. 2. If we error out, we do not call kunit_handle_shutdown(). This makes kunit.py timeout when using a non-UML arch, since the QEMU process doesn't ever exit.
