Subject: [PATCH v1 1/3] kunit: Do not pollute source directory with generated files (.kunitconfig)
Date: Thu, 15 Oct 2020 18:23:46 +0300	[thread overview]
Message-ID: <20201015152348.65147-1-andriy.shevchenko@linux.intel.com> (raw)

When --build_dir is provided use it and do not pollute source directory
which even can be mounted over network or read-only.
