Subject: [PATCH v6 06/12] kbuild: deb-pkg: make .orig tarball a hard link if possible
Date: Wed, 15 Feb 2023 10:20:28 +0900	[thread overview]
Message-ID: <20230215012034.403356-6-masahiroy@kernel.org> (raw)
In-Reply-To: <20230215012034.403356-1-masahiroy@kernel.org>

If '..' belongs to the same filesystem, create a hard link instead of
a copy. In most cases, you can save disk space.

I do not want to use 'mv' because keeping linux.tar.gz is useful to
avoid unneeded rebuilding of the tarball.
