Subject: [PATCH v2 05/13] nvme-multipath: add nvme_mpath_is_{disabled, optimised}
Date: Tue, 28 Apr 2026 11:12:48 +0000	[thread overview]
Message-ID: <20260428111256.1778475-6-john.g.garry@oracle.com> (raw)
In-Reply-To: <20260428111256.1778475-1-john.g.garry@oracle.com>

These are for mpath_head_template.is_{disabled, optimized} callbacks, and
just call into nvme_path_is_disabled() and nvme_path_is_optimized(),
respectively.
