      Pull HID updates from Jiri Kosina:
      
       - Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada
      
       - Big cleanup of Wacom driver; namely it's now using devres, and the
         standardized LED API so that libinput doesn't need to have root
         access any more, with substantial amount of other cleanups
         piggy-backing on top. All this from Benjamin Tissoires
      
       - Report descriptor parsing would now ignore and out-of-range System
         controls in case of the application actually being System Control.
         This fixes quite some issues with several devices, and allows us to
         remove a few ->report_fixup callbacks. From Benjamin Tissoires

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've investigated how f2fs deals with errors given by
        our fault injection facility. With this, we could fix several corner
        cases. And, in order to improve the performance, we set inline_dentry
        by default and enhance the exisiting discard issue flow. In addition,
        we added f2fs_migrate_page for better memory management.
      
        Enhancements:
         - set inline_dentry by default
         - improve discard issue flow
         - add more fault injection cases in f2fs
         - allow block preallocation for encrypted files
         - introduce migrate_page callback function
         - avoid truncating the next direct node block at every checkpoint
      
        Bug fixes:
         - set page flag correctly between write_begin and write_end
         - missing error handling cases detected by fault injection
         - preallocate blocks regarding to 4KB alignement correctly

      Pull namespace updates from Eric Biederman:
       "This set of changes is a number of smaller things that have been
        overlooked in other development cycles focused on more fundamental
        change. The devpts changes are small things that were a distraction
        until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an
        trivial regression fix to autofs for the unprivileged mount changes
        that went in last cycle. A pair of ioctls has been added by Andrey
        Vagin making it is possible to discover the relationships between
        namespaces when referring to them through file descriptors.
      
        The big user visible change is starting to add simple resource limits
        to catch programs that misbehave. With namespaces in general and user
        namespaces in particular allowing users to use more kinds of
        resources, it has become important to have something to limit errant
        programs. Because the purpose of these limits is to catch errant
        programs the code needs to be inexpensive to use as it always on, and
        the default limits need to be high enough that well behaved programs
        on well behaved systems don't encounter them.
      
        To this end, after some review I have implemented per user per user
        namespace limits, and use them to limit the number of namespaces. The
        limits being per user mean that one user can not exhause the limits of
        another user. The limits being per user namespace allow contexts where
        the limit is 0 and security conscious folks can remove from their
        threat anlysis the code used to manage namespaces (as they have
        historically done as it root only). At the same time the limits being
        per user namespace allow other parts of the system to use namespaces.
      
        Namespaces are increasingly being used in application sand boxing
        scenarios so an all or nothing disable for the entire system for the
        security conscious folks makes increasing use of these sandboxes
        impossible.
      
        There is also added a limit on the maximum number of mounts present in
        a single mount namespace. It is nontrivial to guess what a reasonable
        system wide limit on the number of mount structure in the kernel would
        be, especially as it various based on how a system is using
        containers. A limit on the number of mounts in a mount namespace
        however is much easier to understand and set. In most cases in
        practice only about 1000 mounts are used. Given that some autofs
        scenarious have the potential to be 30,000 to 50,000 mounts I have set
        the default limit for the number of mounts at 100,000 which is well
        above every known set of users but low enough that the mount hash
        tables don't degrade unreaonsably.
      
        These limits are a start. I expect this estabilishes a pattern that
        other limits for resources that namespaces use will follow. There has
        been interest in making inotify event limits per user per user
        namespace as well as interest expressed in making details about what
        is going on in the kernel more visible"

      Pull xfs and iomap updates from Dave Chinner:
       "The main things in this update are the iomap-based DAX infrastructure,
        an XFS delalloc rework, and a chunk of fixes to how log recovery
        schedules writeback to prevent spurious corruption detections when
        recovery of certain items was not required.
      
        The other main chunk of code is some preparation for the upcoming
        reflink functionality. Most of it is generic and cleanups that stand
        alone, but they were ready and reviewed so are in this pull request.
      
        Speaking of reflink, I'm currently planning to send you another pull
        request next week containing all the new reflink functionality. I'm
        working through a similar process to the last cycle, where I sent the
        reverse mapping code in a separate request because of how large it
        was. The reflink code merge is even bigger than reverse mapping, so
        I'll be doing the same thing again....
      
        Summary for this update:
      
         - change of XFS mailing list to linux-xfs@vger.kernel.org
      
         - iomap-based DAX infrastructure w/ XFS and ext2 support
      
         - small iomap fixes and additions
      
         - more efficient XFS delayed allocation infrastructure based on iomap
      
         - a rework of log recovery writeback scheduling to ensure we don't
           fail recovery when trying to replay items that are already on disk
      
         - some preparation patches for upcoming reflink support
      
         - configurable error handling fixes and documentation
      
         - aio access time update race fixes for XFS and
           generic_file_read_iter"
