Subject: [PATCH v1] selftests: Use optional USERCFLAGS and USERLDFLAGS
Date: Fri,  9 Sep 2022 12:39:01 +0200	[thread overview]
Message-ID: <20220909103901.1503436-1-mic@digikod.net> (raw)

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.
