I'm not so sure about that. The reason that the messages are printed now is that there is no fallback handler for these ioctl numbers any more, but they are instead expected to be handled by the compat_blkdev_ioctl() function, which is only called for block devices. My first idea was that the ioctl numbers are used on files that are not block devices, in this case the warning message would be (somewhat) appropriate. Whenever we get one of these messages on a real block device, that is supposed to mean that an ioctl that was actually valid could not be executed, and compat_blkdev_ioctl() returned -ENOIOCTLCMD.
