Drat... for some reason I was thinking that it only came in in 2.6.31-rc.
However it is only documented in ABI/testing, not ABI/stable ... if there
is any value in that distinction, then it should be possible to move it??

Well, maybe I'm too late.
If I send you a patch to remove all those fields in 'queue' that are not
relevant to md/dm (when the queue is used for an md/dm device) would that
be OK ??
