Subject: [PATCH v4 03/19] selftests/resctrl: Unmount resctrl FS if child fails to run benchmark
Date: Thu, 13 Jul 2023 16:19:16 +0300 [thread overview]
Message-ID: <20230713131932.133258-4-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230713131932.133258-1-ilpo.jarvinen@linux.intel.com>
A child calls PARENT_EXIT() when it fails to run a benchmark to kill
the parent process. PARENT_EXIT() lacks unmount for the resctrl FS and
the parent won't be there to unmount it either after it gets killed.
Add the resctrl FS unmount also to PARENT_EXIT().
Fixes: 591a6e8588fc ("selftests/resctrl: Add basic resctrl file system operations and data")
