Doug, the thing to do here is to rework your recent mqueue patchset.
Prepare a minimal, critical-stuff series of bugfix patches against
current Linus mainline which is also applicable to -stable. We can
merge that into 3.1 or, more likely, into 3.2-rc1/3.1.x.

Then, later, we can merge up the less critical parts of that patchset.

otoh, the only not-applicable-to-stable part of that patchset appears
to be "[1/5] ipc/mqueue: cleanup definition names and locations" and
it's fairly small. So we could perhaps just merge all five into
3.2-rc1, with a -stable backport.

Doing that backport would require that we first backport the buggy
patches (ie: this one), which is a bit weird. Perhaps it would be
better for you to prepare a reworked patch series for 3.0.x after
that five-patch series hits mainline.
