From 2a2dfc869d3345ccdd91322b023f4b0da84acbe7 Mon Sep 17 00:00:00 2001 From: Joe Fradley Date: Tue, 23 Aug 2022 21:19:33 -0700 Subject: tools: Add new "test" taint to kernel-chktaint Commit c272612cb4a2 ("kunit: Taint the kernel when KUnit tests are run") added a new taint flag for when in-kernel tests run. This commit adds recognition of this new flag in kernel-chktaint. With this change the correct reason will be reported if the kernel is tainted because of a test run.
