Did this include sleeping spinlocks? My understanding has been that these are the ugly duckling of the PREEMPT_RT tree that the rest of the kernel developers would rather not see in mainline.

Or did you mean the part of the -rt patch that automagically turns most spinlocks into such adaptive mutexes (w/ PI)? Yeah, that might be more difficult to get into mainline?
