Hello,

This series is to support I/O passthrough for multipath I/O.

Currently driver exposes block device for the head namespace.  Also, the
path will be decided by the driver with the I/O policy defined to the
actual hidden device based on ANA state.  This means that userspace is not
allowed to I/O passthrough to a specified namespace target which is hidden
by the driver.

This series is to support passthrough to the namespace attached to a
controller regardless to ANA state (e.g., inaccessible) and decided path
by the driver.

Please review.

Thanks,
