KDBUS Won't Be Pushed Until The Linux 4.3 Kernel

KDBUS was once again heavily debated on the Linux kernel mailing list this week and Linus Torvalds said he looked forward to merging it when ready (and also had some choice words about performance). However, Greg KH has confirmed today that KDBUS isn't ready for merging this cycle.

Greg Kroah-Hartman posted a short time ago that he isn't going to send in a pull request for this in-kernel IPC mechanism for Linux 4.2. However, it looks like it will be ready for Linux 4.3.
We (David, Daniel, Djalal, and myself) do not need to rush anything and will be delaying the kdbus merge request for another cycle. There still seems to be some disagreement and we are confident that with more time to review this can be sorted out. We have asked distributions to start testing kdbus and have already gotten back valuable feedback from real world testing. We are incorporating that feedback, fixing bugs, and optimizing some internal details which will all be part of the pull request for the next release cycle.
