Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-4.9-fs-rc2-tag

I have separated these fixes out from the previous set because they
contain changes to generic filesystem code.  Despite reposts and pings,
these changes got no response from the relevant maintainer.

I think the changes are trivial and uncontroversial.  Please consider
merging.

xen: xenfs fixes for 4.9-rc2

- - Fix issues with simultaneous writes and reads to /proc/xen/xenbus.
- - Fix /proc/xen inside filesystem namespaces.

Thanks.

David
