Subject: [PATCH] bug: fix warning suppressions with kunit built as module
Date: Tue,  7 Jul 2026 14:58:37 +0200	[thread overview]
Message-ID: <20260707125837.57256-1-bartosz.golaszewski@oss.qualcomm.com> (raw)

CONFIG_KUNIT is a tristate symbol but the warning suppression code in
lib/bug.c is only built if it's built-in. Use IS_ENABLE(CONFIG_KUNIT) to
enable it for a loadable kunit module as well. When using a plain #ifdef,
the suppressions only work if kunit is built-in.

Cc: stable@vger.kernel.org
Fixes: 85347718ab0d ("bug/kunit: Core support for suppressing warning backtraces")
