Subject: [PATCH 09/10] kconfig: refactor conf_touch_dep()
Date: Fri, 1 Oct 2021 14:32:52 +0900 [thread overview]
Message-ID: <20211001053253.1223316-9-masahiroy@kernel.org> (raw)
In-Reply-To: <20211001053253.1223316-1-masahiroy@kernel.org>
If this function fails to touch a dummy header due to missing parent
directory, then it creates it and touches the file again.
This was needed because CONFIG_FOO_BAR was previously tracked by
include/config/foo/bar.h. (include/config/foo/ may not exist here)
This is no longer the case since commit 0e0345b77ac4 ("kbuild: redo
fake deps at include/config/*.h"); now all the fake headers are placed
right under include/config/, like include/config/FOO_BAR.
Do not try to create parent directory, include/config/, which already
exists.
