Subject: [PATCH V2 11/19] selftests/resctrl: Abort running tests if not root user
Date: Mon, 18 May 2020 15:08:31 -0700
Message-ID: <e8bed1e4ec3b294926670190beb863b1caa3fceb.1589835155.git.sai.praneeth.prakhya@intel.com> (raw)
In-Reply-To: <cover.1589835155.git.sai.praneeth.prakhya@intel.com>

Running resctrl selftest requires the test to write to resctrl file system
and only root user has permission to do so. Hence, abort the test suite if
the user is not running the test with root user privileges.

Fixes: ecdbb911f22d ("selftests/resctrl: Add MBM test")
