From 4a0ef6078731cac11cdde5e5f355f2252828eb56 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Wed, 14 Oct 2026 16:01:37 -0400 Subject: [PATCH] selftests/mm: report the configuration check on stderr The mm Makefile includes local_config.mk, which is generated by a rule that announces itself with "CHK [config] local_config.mk" on standard output, which make -s does not suppress. When make has to regenerate the file while it reads the Makefile for emit_tests, for example on a fresh tree or when the selftests are installed with make -B, the message becomes part of the emit_tests output that the selftests install target appends to kselftest-list.txt, so the runlist gains a line that is not a test. Print the message on standard error. With V=1 the message is empty and only the redirection of an empty command remains.
