[dm-devel] [PATCH 6/6] nvme: allow revalidate to set a namespace read-only

[Christoph Hellwig]

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.
