[PATCH 0/2] nvmet: improve 'read-only' handling

[Hannes Reinecke]

Hi all,

there was a request (Hi Lennart) to implement 'readonly' handling
for nvme target. Turns out to be relatively easy as we already have
a 'readonly' flag for the namespace.
So all what's left is to make this flag settable via a new configfs
attribute. And while at it we can as well check if the underlying
device/file is read-only, and implement a 'persistent_ro' flag to
mark them as persistently read-only.

As usual, comments and reviews are welcome.
