Subject: [PATCH 4.9 21/31] kbuild: Fix include path in scripts/Makefile.modpost
Date: Fri, 2 Sep 2022 14:18:47 +0200 [thread overview]
Message-ID: <20220902121357.540870777@linuxfoundation.org> (raw)
In-Reply-To: <20220902121356.732130937@linuxfoundation.org>
From: Jing Leng <jleng@ambarella.com>
commit 23a0cb8e3225122496bfa79172005c587c2d64bf upstream.
When building an external module, if users don't need to separate the
compilation output and source code, they run the following command:
"make -C $(LINUX_SRC_DIR) M=$(PWD)". At this point, "$(KBUILD_EXTMOD)"
and "$(src)" are the same.
If they need to separate them, they run "make -C $(KERNEL_SRC_DIR)
O=$(KERNEL_OUT_DIR) M=$(OUT_DIR) src=$(PWD)". Before running the
command, they need to copy "Kbuild" or "Makefile" to "$(OUT_DIR)" to
prevent compilation failure.
So the kernel should change the included path to avoid the copy operation.

[masahiro: I do not think "M=$(OUT_DIR) src=$(PWD)" is the official way,
but this patch is a nice clean up anyway.]
