From b36b990c50b1f581b9a7f35ae256f5542415fa69 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Wed, 14 Oct 2026 16:01:35 -0400 Subject: [PATCH] selftests/exec: report the skipped binfmt_misc_bpf test on stderr The exec Makefile announces that binfmt_misc_bpf is skipped with $(info), which writes to standard output whenever the Makefile is parsed. The selftests install target appends the standard output of "make -s emit_tests" to kselftest-list.txt, so on systems without the BPF toolchain the runlist gains a line that is not a test entry: exec selftests: skipping binfmt_misc_bpf, needs clang, bpftool, ... run_kselftest.sh and CI systems that parse the runlist then treat it as a malformed test entry. Use $(warning) so that the notice still appears in build logs but goes to standard error.
