Subject: [PATCH] kbuild: show warning for 'make headers_check'
Date: Tue, 2 Mar 2021 23:26:14 +0900 [thread overview]
Message-ID: <20210302142614.505888-1-masahiroy@kernel.org> (raw)
Since commit 7ecaf069da52 ("kbuild: move headers_check rule to
usr/include/Makefile"), the headers_check target is no-op.
This stub target is remaining here in case some scripts still invoke
'make headers_check'. 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.
