A couple of comments:

No need for the "." the end of the subject line.

I also think you should just talk of the nvme_user_cmd function,
as that also is used for the NVME_IOCTL_IO_CMD ioctl.  Also there now
is a nvme_user_cmd64 variant that needs the same fix, can you also
include that?

s/real //g please, there are no fake 32-vit kernels :)
