There's no such thing as first or second class block devices. The fact
that drivers using ->make_request_fn directly do not utilize the full
scope of the queue isn't a very interesting fact, imho.

 Your phrase "drivers using ->make_request_fn directly" seems to
 suggest you are looking at things very differently to me.

 From my perspective, all drivers use ->make_request_fn equally.
 Some set it to "__make_request", some to "md_make_request", others to
 "dm_request" or "loop_make_request" etc.

Neil, will you please stop these silly games. Stop trying to invent
differences based on interpretations of what you read into my replies.

We do seem to be having trouble communicating don't we :-(
Be assured that it is not my intention to play games, silly or otherwise.

Maybe I should just try sending you patches.  Maybe that will
make my meaning clearer.

For the moment, I'm much more interested in the other question,
that of whether I can avoid having a 'queue' directory introduced into
md/dm/etc device directories in sysfs.
