Subject: [PATCH v5 0/6] nvme: add csi, ms and nuse to sysfs

I've added two new refactoring patches which convert a bunch of functions to
accpet nvme_ns_head instead of nvme_ns. Though I've left out the conversion of
nvme_update_ns_info_block because there are still users of nvme_ns deeper down
the callchain.

Besides this I've addressed all comments from v4, remove debug output, silence
ratelimit messages and revert the nvme_ns_head coversion in
nvme_zns_alloc_report_buffer.

The benchmark numbers are still roughly the same and all blktests for all
transports pass with this change. My previous claim in v3 that something is
broken for rdma turned out it's my test that setup was b0rken.

Thanks,
Daniel
