That merge will shave off a large portion of the rt patch (don't worry, we have enough new and exiting stuff in the pipeline to keep the patch size large enough) - fixing RCU assumptions in mainline and backport to 31-rt - lots of brain twisting around the POSIX scheduling policy compliance problems which got reported vs. Priority Inheritance/Protection - an extended christmas break and the resulting email backlog - our new housemate: http://tglx.de/~tglx/housemate.png Further plans: - a last big feature for 31-rt is pending, which is worth a separate release: Nick Piggins VFS scalability patches. I'm still running tests on that, so no promise. - I'm going to switch 31-rt into maintaince mode (with or without the VFS patches) and concentrate on getting .33-rcX-rt out. Yes, there will be no .32-rt. The reason is simply that the locking changes which got merged into .33 are making my life easier and are the base to sort out more ready for the mainline stuff.
