      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'
      
         - one minor change to the kobject code acked by Greg KH"

      Pull dma mapping updates from Christoph Hellwig:
       "Except for a runtime warning fix from Christian this is all about
        consolidation of the generic no-IOMMU code, a well as the glue code
        for swiotlb.
      
        All the code is based on the x86 implementation with hooks to allow
        all architectures that aren't cache coherent to use it.
      
        The x86 conversion itself has been deferred because the x86
        maintainers were a little busy in the last months"

      Pull SCSI updates from James Bottomley:
       "This is mostly updates of the usual driver suspects: arcmsr,
        scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
        hisi_sas.
      
        We also have a rework of the libsas hotplug handling to make it more
        robust, a slew of 32 bit time conversions and fixes, and a host of the
        usual minor updates and style changes. The biggest potential for
        regressions is the libsas hotplug changes, but so far they seem stable
        under testing"

      Pull device mapper updates from Mike Snitzer:
      
       - 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.
      
         - Remove EXPERIMENTAL tag from reflink!"
