Message-Id: <20250429-ublk_selftests-v2-1-e970b6d9e4f4@purestorage.com> Date: Tue, 29 Apr 2025 16:41:03 -0600 From: Uday Shankar <ushankar@...estorage.com> To: Ming Lei <ming.lei@...hat.com>, Shuah Khan <shuah@...nel.org> Cc: linux-block@...r.kernel.org, linux-kselftest@...r.kernel.org, linux-kernel@...r.kernel.org, Uday Shankar <ushankar@...estorage.com> Subject: [PATCH v2 1/3] selftests: ublk: kublk: build with -Werror iff WERROR!=0 Compiler warnings can catch bugs at compile time; thus, heeding them is usually a good idea. Turn warnings into errors by default for the kublk build so that anyone making changes is forced to heed them. Compiler warnings can also sometimes produce annoying false positives, so provide a flag WERROR that the developer can use as follows to have the build and selftests run go through even if there are warnings: make WERROR=0 TARGETS=ublk kselftest Signed-off-by: Uday Shankar <ushankar@...estorage.com> --- tools/testing/selftests/ublk/Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tools/testing/selftests/ublk/Makefile b/tools/testing/selftests/ublk/Makefile index ec4624a283bce2ebeed80509be6573c1b7a3623d..529ab98a2633a2278bc0df8b26500905d60d2bec 100644 --- a/tools/testing/selftests/ublk/Makefile +++ b/tools/testing/selftests/ublk/Makefile @@ -1,6 +1,10 @@ # SPDX-License-Identifier: GPL-2.0 CFLAGS += -O3 -Wl,-no-as-needed -Wall -I $(top_srcdir) +ifneq ($(WERROR),0) + CFLAGS += -Werror +endif + LDLIBS += -lpthread -lm -luring TEST_PROGS := test_generic_01.sh -- 2.34.1
