From 609bbb4de4f85b7ef45d81a88e6b7dfe3bf5ccea Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 2 Mar 2021 23:26:14 +0900 Subject: [PATCH] kbuild: show warning if 'make headers_check' is used Since commit 7ecaf069da52 ("kbuild: move headers_check rule to usr/include/Makefile"), 'make headers_check' is no-op. This stub target is remaining here in case some scripts still invoke it. In order to prompt people to remove stale code, show a noisy warning message if used. The stub will be really removed after the Linux 5.15 release.
