       "Bruce has announced he is leaving Red Hat at the end of the month and
        is stepping back from his role as NFSD co-maintainer. As a result,
        this includes a patch removing him from the MAINTAINERS file.
      
        There is one patch in here that Jeff Layton was carrying in the locks
        tree. Since he had only one for this cycle, he asked us to send it to
        you via the nfsd tree.
      
        There continues to be 0-day reports from Robert Morris @MIT. This time
        we include a fix for a crash in the COPY_NOTIFY operation.
      
        Highlights:
         - Bruce steps down as NFSD maintainer
         - Prepare for dynamic nfsd thread management
         - More work on supporting re-exporting NFS mounts
         - One fs/locks patch on behalf of Jeff Layton

      Linus Torvalds authored
      Pull memblock cleanup from Mike Rapoport:
       "Remove #ifdef __KERNEL__ from memblock.h
      
        memblock.h is not a uAPI header, so __KERNEL__ guard can be deleted"
