The bulk of this pull request is a major rework that Darrick and Christoph have been doing on XFS's real-time volume, coupled with a few features to support this rework. It does also includes some bug fixes. Those patches are in linux-next for a few days already, and I just did a trial merge on your TOT, and didn't see any conflicts. This is the firs merge window I'm working on, if something needs to be improved in the pull request, please let me know.
