[PATCH V2 0/1] nvme: fix controller ioctl through ns_head

[Minwoo Im]

Hello,

This series is to fix controller ioctl through the ns_head block device
and the per-namespace generic device.  This patch is mostly manual
revert for the commit 3557a4409701 ("nvme: don't bother to look up a
namespace for controller ioctls") with few more updates to the generic
device.

Please review.

Thanks,

Since V1:
  - Manually revert 3557a4409701 ("nvme: don't bother to look up a
    namespace for controller ioctls").  (Christoph)
  - Updates nvme_ns_head_chr_ioctl() which has been newly added for
    generic per-namespace chardev.
