While we're at the topic:

Can't we use the same names for legacy and mq scheduler?
It's quite an unnecessary complication to have
'noop', 'deadline', and 'cfq' for legacy, but 'none' and 'mq-deadline'
for mq. If we could use 'noop' and 'deadline' for mq, too, the existing
settings or udev rules will continue to work and we wouldn't get any
annoying and pointless warnings here...

I mentioned this to Jens a little while ago but I didn't feel strongly
enough to push the issue. I also like this idea -- it makes the
transition to blk-mq a little more transparent.
