From d1d73c303458a148f8b77fca99aa71074c69eb49 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micka=C3=ABl=20Sala=C3=BCn?= Date: Fri, 9 Sep 2022 12:39:01 +0200 Subject: [PATCH] selftests: Use optional USERCFLAGS and USERLDFLAGS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit de3ee3f63400a23954e7c1ad1cb8c20f29ab6fe3 upstream. This change enables to extend CFLAGS and LDFLAGS from command line, e.g. to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static USERCFLAGS and USERLDFLAGS are documented in Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst This should be backported (down to 5.10) to improve previous kernel versions testing as well.
