   2
   3 I/O is submitted to an NVMe namespace using nvme_ns_cmd_xxx functions
   4 defined in nvme_ns_cmd.c.  The NVMe driver submits the I/O request
   5 as an NVMe submission queue entry on the queue pair specified in the command.
   6 The application must poll for I/O completion on each queue pair with outstanding I/O
   7 to receive completion callbacks.
