From 363f6368603743072e5f318c668c632bccb097a3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 16 Feb 2022 15:07:15 +0100 Subject: [PATCH] nvme: don't return an error from nvme_configure_metadata When a fabrics controller claims to support an invalidate metadata configuration we already warn and disable metadata support. No need to also return an error during revalidation.
