Dear RT Folks, This is the RT stable review cycle of patch 3.18.27-rt26-rc1.
Please scream at me if I messed something up. Please test the patches too. Note, I'm bringing this tree up to stable patches in 4.1.7-rt8. Then I'll be pulling 4.1-rt into stable, as development is now on 4.4-rt. After that, I'll be pulling the 4.1-rt stable changes into the stable trees. The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate). The pre-releases will not be pushed to the git repository, only the final release is. If all goes well, this patch will be converted to the next main release on 2/29/2016.
