From: Mateusz Kusiak <mateusz.kusiak@intel.com>
Date: Mon, 2 Jan 2023 09:35:15 +0100
Subject: [PATCH] mdadm: Add option validation for --update-subarray
Subset of options available for "--update" is not same as for "--update-subarray".
Define maps and enum for update options and use them instead of direct comparisons.
Add proper error message.
