      Pull GPIO updates from Linus Walleij:
       "The is the bulk of GPIO changes for the v4.16 kernel cycle. It is
        pretty calm this time around I think. I even got time to get to things
        like starting to clean up header includes.
      
        Core changes:
      
         - Disallow open drain and open source flags to be set simultaneously.
           This doesn't make electrical sense, and would the hardware actually
           respond to this setting, the result would be short circuit.
      
         - ACPI GPIO has a new core infrastructure for handling quirks. The
           quirks are there to deal with broken ACPI tables centrally instead
           of pushing the work to individual drivers. In the world of BIOS
           writers, the ACPI tables are perfect. Until they find a mistake in
           it. When such a mistake is found, we can patch it with a quirk. It
           should never happen, the problem is that it happens. So we
           accomodate for it.
      
         - Several documentation updates.
      
         - Revert the patch setting up initial direction state from reading
           the device. This was causing bad things for drivers that can't read
           status on all its pins. It is only affecting debugfs information
           quality.
      
         - Label descriptors with the device name if no explicit label is
           passed in.
      
         - Pave the ground for transitioning SPI and regulators to use GPIO
           descriptors by implementing some quirks in the device tree GPIO
           parsing code.
      
        New drivers:
      
         - New driver for the Access PCIe IDIO 24 family.
      
        Other:
      
         - Major refactorings and improvements to the GPIO mockup driver used
           for test and verification.
      
         - Moved the AXP209 driver over to pin control since it gained a pin
           control back-end. These patches will appear (with the same hashes)
           in the pin control pull request as well.
      
         - Convert the onewire GPIO driver w1-gpio to use descriptors. This is
           merged here since the W1 maintainers send very few pull requests
           and he ACKed it.
      
         - Start to clean up driver headers using <linux/gpio.h> to just use
           <linux/gpio/driver.h> as appropriate"

      Pull RDMA subsystem updates from Jason Gunthorpe:
       "Overall this cycle did not have any major excitement, and did not
        require any shared branch with netdev.
      
        Lots of driver updates, particularly of the scale-up and performance
        variety. The largest body of core work was Parav's patches fixing and
        restructing some of the core code to make way for future RDMA
        containerization.
      
        Summary:
      
         - misc small driver fixups to
           bnxt_re/hfi1/qib/hns/ocrdma/rdmavt/vmw_pvrdma/nes
      
         - several major feature adds to bnxt_re driver: SRIOV VF RoCE
           support, HugePages support, extended hardware stats support, and
           SRQ support
      
         - a notable number of fixes to the i40iw driver from debugging scale
           up testing
      
         - more work to enable the new hip08 chip in the hns driver
      
         - misc small ULP fixups to srp/srpt//ipoib
      
         - preparation for srp initiator and target to support the RDMA-CM
           protocol for connections
      
         - add RDMA-CM support to srp initiator, srp target is still a WIP
      
         - fixes for a couple of places where ipoib could spam the dmesg log
      
         - fix encode/decode of FDR/EDR data rates in the core
      
         - many patches from Parav with ongoing work to clean up
           inconsistencies and bugs in RoCE support around the rdma_cm
      
         - mlx5 driver support for the userspace features 'thread domain',
           'wallclock timestamps' and 'DV Direct Connected transport'. Support
           for the firmware dual port rocee capability
      
         - core support for more than 32 rdma devices in the char dev
           allocation
      
         - kernel doc updates from Randy Dunlap
      
         - new netlink uAPI for inspecting RDMA objects similar in spirit to 'ss'

       - DM core fixes to ensure that bio submission follows a depth-first
         tree walk; this is critical to allow forward progress without the
         need to use the bioset's BIOSET_NEED_RESCUER.
      
       - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
      
       - DM core cleanups and improvements to make bio-based DM more efficient
         (e.g. reduced memory footprint as well leveraging per-bio-data more).
      
       - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
         the more direct IO submission path in the block layer; this mode is
         used by DM multipath and also optimizes targets like DM thin-pool
         that stack directly on NVMe data device.
      
       - DM multipath improvements to factor out legacy SCSI-only (e.g.
         scsi_dh) code paths to allow for more optimized support for NVMe
         multipath.
      
       - A fix for DM multipath path selectors (service-time and queue-length)
         to select paths in a more balanced way; largely academic but doesn't
         hurt.
      
       - Numerous DM raid target fixes and improvements.
      
       - Add a new DM "unstriped" target that enables Intel to workaround
         firmware limitations in some NVMe drives that are striped internally
         (this target also works when stacked above the DM "striped" target).
      
       - Various Documentation fixes and improvements.
      
       - Misc cleanups and fixes across various DM infrastructure and targets
         (e.g. bufio, flakey, log-writes, snapshot).

      Pull xfs updates from Darrick Wong:
       "This merge cycle, we're again some substantive changes to XFS.
      
        Metadata verifiers have been restructured to provide more detail about
        which part of a metadata structure failed checks, and we've enhanced
        the new online fsck feature to cross-reference extent allocation
        information with the other metadata structures. With this pull, the
        metadata verification part of online fsck is more or less finished,
        though the feature is still experimental and still disabled by
        default.
      
        We're also preparing to remove the EXPERIMENTAL tag from a couple of
        features this cycle. This week we're committing a bunch of space
        accounting fixes for reflink and removing the EXPERIMENTAL tag from
        reflink; I anticipate that we'll be ready to do the same for the
        reverse mapping feature next week. (I don't have any pending fixes for
        rmap; however I wish to remove the tags one at a time.)
      
        This giant pile of patches has been run through a full xfstests run
        over the weekend and through a quick xfstests run against this
        morning's master, with no major failures reported. Let me know if
        there's any merge problems -- git merge reported that one of our
        patches touched the same function as the i_version series, but it
        resolved things cleanly.
      
        Summary:
      
         - Log faulting code locations when verifiers fail, for improved
           diagnosis of corrupt filesystems.
      
         - Implement metadata verifiers for local format inode fork data.
      
         - Online scrub now cross-references metadata records with other
           metadata.
      
         - Refactor the fs geometry ioctl generation functions.
      
         - Harden various metadata verifiers.
      
         - Fix various accounting problems.
      
         - Fix uncancelled transactions leaking when xattr functions fail.
      
         - Prevent the copy-on-write speculative preallocation garbage
           collector from racing with writeback.
      
         - Emit log reservation type information as trace data so that we can
           compare against xfsprogs.
      
         - Fix some erroneous asserts in the online scrub code.
      
         - Clean up the transaction reservation calculations.
      
         - Fix various minor bugs in online scrub.
      
         - Log complaints about mixed dio/buffered writes once per day and
           less noisily than before.
      
         - Refactor buffer log item lists to use list_head.
      
         - Break PNFS leases before reflinking blocks.
      
         - Reduce lock contention on reflink source files.
      
         - Fix some quota accounting problems with reflink.
      
         - Fix a serious corruption problem in the direct cow write code where
           we fed bad iomaps to the vfs iomap consumers.
      
         - Various other refactorings.

       "We've got 30 patches for this merge window. These generally fall into
        five categories:
      
         - code cleanups
      
         - patches related to adding PUNCH_HOLE support to GFS2
      
         - support for new fields in resource group headers
      
         - a few bug fixes
      
         - support for new fields in journal log headers. These new fields,
           which were previously unused, are designed to make it easier to
           track down file system corruption, and allow fsck.gfs2 to make more
           intelligent decisions when finding and fixing file system
           corruption.
      
        Details:
      
         - Two patches from Abhi Das, to trim the ordered writes list, which
           used to grow uncontrollably until unmount.
      
         - Several patches from Andreas Gruenbacher: remove an unused
           parameter from function gfs2_write_jdata_pagevec, remove a
           pointless BUG_ON, clean up an error patch in trunc_start, remove
           some unused parameters from truncate, make gfs2_journaled_truncate
           more efficient, clean up the support functions for truncate, fix
           metadata read-ahead for truncate to make it faster, fix up the
           non-recursive truncate code, rework and rename
           gfs2_block_truncate_page, generalize the non-recursive truncate
           code so it can take a range of values for punch_hole support,
           introduce new PUNCH_HOLE support that take advantage of the
           previous patches, add fallocate support with PUNCH_HOLE, fix some
           typos in the comments, add the function gfs2_max_stuffed_size to
           replace a piece of code that was needlessly repeated throughout
           GFS2, a minor cleanup to function gfs2_page_add_databufs, get rid
           of function gfs2_log_header_in in preparation for the new log
           header fields, and also fix up some missing newlines in kernel
           messages.
      
         - Andy Price added a new field to resource groups to indicate where
           the next one should be, to allow fsck.gfs2 to make better repairs.
           He also added new rindex fields for consistency checking, and added
           a crc field to resource group headers for consistency checking.
      
         - I reduced redundancy in functions common to freeing dinodes, and
           when writing log headers between the journalling code and journal
           recovery code. Also added new fields to journal log headers based
           on a prototype from Steve Whitehouse, and log the source of journal
           log headers so we can better track down journal corruption. Minor
           comment typo fix and a fix for a BUG in an unlink error path.
      
         - Steve Whitehouse contributed a patch to fix an incorrect use of the
           gfs2_blk2rgrpd function.
      
         - Tetsuo Handa contributed a patch that fixes incorrect error

      iversion: make inode_cmp_iversion{+raw} return bool instead of s64 · c0cef30e
      Jeff Layton authored
      As Linus points out:
      
          The inode_cmp_iversion{+raw}() functions are pure and utter crap.
      
          Why?
      
          You say that they return 0/negative/positive, but they do so in a
          completely broken manner. They return that ternary value as the
          sequence number difference in a 's64', which means that if you
          actually care about that ternary value, and do the *sane* thing that
          the kernel-doc of the function implies is the right thing, you would
          do
      
              int cmp = inode_cmp_iversion(inode, old);
              if (cmp < 0 ...
      
          and as a result you get code that looks sane, but that doesn't
          actually *WORK* right.
      
      Since none of the callers actually care about the ternary value here,
      convert the inode_cmp_iversion{+raw} functions to just return a boolean
      value (false for matching, true for non-matching).
      
      This matches the existing use of these functions just fine, and makes it
      simple to convert them to return a ternary value in the future if we
      grow callers that need it.
      
      With this change we can also reimplement inode_cmp_iversion in a simpler
      way using inode_peek_iversion.

      Jiri Kosina authored
      Pull Wacom device driver updates. These don't have to go on top of the
      hid_have_special_driver[] revamp, as the whole group is assumed to
      have a special driver based on VID.

      This series from Benjamin Tissoires finally removes one of the big PITAs
