[PATCH v3 0/4] nvme: add csi, ms and nuse to sysfs

[Daniel Wagner <dwagner@suse.de>]

I'v dropped the RFC status and tested it lot more which found an obvious bug.
When initializating the disk in nvme_alloc_ns, the ns->head pointer was still
NULL. This is why I added the 'nvme: initialize head before namespace' patch.

I can't really explain why my testing didn't catch this earlier. Anyway, I
rebuild my test setup completely to make sure I got the most obvious things
tested. The blktests with loop and nvme-tcp pass, nvme-rdma breaks but so does
the base line test. So not a regression by this series.

Thanks,
Daniel
