Subject: [bpf-next PATCH v2 1/4] kbuild: remove ARCH_POSTLINK from module builds
Date: Thu, 19 Oct 2023 00:19:47 +0900 [thread overview]
Message-ID: <20231018151950.205265-1-masahiroy@kernel.org> (raw)
The '%.ko' rule in arch/*/Makefile.postlink does nothing but call the
'true' command.
Remove the meaningless code.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
