Subject: [PATCH 4/8] kbuild: remove $(MODLIB)/source symlink
Date: Wed, 23 Aug 2023 20:50:44 +0900	[thread overview]
Message-ID: <20230823115048.823011-4-masahiroy@kernel.org> (raw)
In-Reply-To: <20230823115048.823011-1-masahiroy@kernel.org>

This reverts the old commit "kbuild: Introduce source symlink in
/lib/modules/.../". [1]

The current Kbuild does not require $(MODLIB)/source. If the kernel was
built in a separate output directory, $(MODLIB)/build/Makefile wraps
the Makefile in the source tree. It is enough for building external
modules.
