From d11cd28998e9d25389d8c20e7cce0e4b4f17bee1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig <hch@lst.de> Date: Sat, 9 Jan 2021 11:42:54 +0100 Subject: [PATCH] nvme: allow revalidate to set a namespace read-only Unconditionally call set_disk_ro now that it only updates the hardware state. This allows to properly set up the Linux devices read-only when the controller turns a previously writable namespace read-only.
