BTW, is it rolandd at cisco.com, rdreier at cisco.com, or both?

I wander why. However, since ipoib workqueue is single-threaded, this gives us
a drastically simple solution to all synchronisation problems, good for
everything that isn't data-path.

Roland, how adding a global, system-wide, single-threaded wq to linux?
We might not be the only ones that have a problem with the default per-CPU
workqueue.
