yes. The kernel/rtmutex.c code which implements user-space PI (the new PI-futexes API) is the exact same code used for preemptible spinlocks too in -rt. It was not entirely trivial to merge the two uses into the same subsystem, but it's reality now. (And i dont want to take all credit for it, large portions of this solution were designed and written by Thomas Gleixner, Esben Nielsen and Steven Rostedt.)
