Subject: [PATCH v4 28/29] selftests/resctrl: Rename resource ID to domain ID
Date: Fri, 15 Dec 2023 17:05:14 +0200	[thread overview]
Message-ID: <20231215150515.36983-29-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20231215150515.36983-1-ilpo.jarvinen@linux.intel.com>

Kernel-side calls the instances of a resource domains.

Change the resource_id naming in the selftest code to domain_id to
match the kernel side better.

Suggested-by: Maciej Wieczór-Retman <maciej.wieczor-retman@intel.com>
