        this time, and fixing a number of quota corners in the process.
      
        Dave Sterba tested and integrated Anand Jain's sysfs improvements.
        Outside of exporting a symbol (ack'd by Greg) these are all internal
        to btrfs and it's mostly cleanups and fixes.  Anand also attached some
        of our sysfs objects to our internal device management structs instead
        of an object off the super block.  It will make device management
        easier overall and it's a better fit for how the sysfs files are used.
        None of the existing sysfs files are moved around.

      cifs: Unset CIFS_MOUNT_POSIX_PATHS flag when following dfs mounts · 1dfd18d0
      Sachin Prabhu authored
      In a dfs setup where the client transitions from a server which supports
      posix paths to a server which doesn't support posix paths, the flag
      CIFS_MOUNT_POSIX_PATHS is not reset. This leads to the wrong directory
      separator being used causing smb commands to fail.
      
      Consider the following case where a dfs share on a samba server points
      to a share on windows smb server.
       # mount -t cifs -o .. //vm140-31/dfsroot/testwin/
       # ls -l /mnt; touch /mnt/a
       total 0
       touch: cannot touch ‘/mnt/a’: No such file or directory

      Fix kmalloc slab creation sequence · a9730fca
      Christoph Lameter authored
      This patch restores the slab creation sequence that was broken by commit
      4066c33d and also reverts the portions that introduced the
      KMALLOC_LOOP_XXX macros. Those can never really work since the slab creation
      is much more complex than just going from a minimum to a maximum number.
      
      The latest upstream kernel boots cleanly on my machine with a 64 bit x86
      configuration under KVM using either SLAB or SLUB.

      Merge tag 'libnvdimm-for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/nvdimm · 88793e5c
      Linus Torvalds authored
      Pull libnvdimm subsystem from Dan Williams:
       "The libnvdimm sub-system introduces, in addition to the
        libnvdimm-core, 4 drivers / enabling modules:
      
        NFIT:
          Instantiates an "nvdimm bus" with the core and registers memory
          devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware
          Interface table).
      
          After registering NVDIMMs the NFIT driver then registers "region"
          devices.  A libnvdimm-region defines an access mode and the
          boundaries of persistent memory media.  A region may span multiple
          NVDIMMs that are interleaved by the hardware memory controller.  In
          turn, a libnvdimm-region can be carved into a "namespace" device and
          bound to the PMEM or BLK driver which will attach a Linux block
          device (disk) interface to the memory.
      
        PMEM:
          Initially merged in v4.1 this driver for contiguous spans of
          persistent memory address ranges is re-worked to drive
          PMEM-namespaces emitted by the libnvdimm-core.
      
          In this update the PMEM driver, on x86, gains the ability to assert
          that writes to persistent memory have been flushed all the way
          through the caches and buffers in the platform to persistent media.
          See memcpy_to_pmem() and wmb_pmem().
      
        BLK:
          This new driver enables access to persistent memory media through
          "Block Data Windows" as defined by the NFIT.  The primary difference
          of this driver to PMEM is that only a small window of persistent
          memory is mapped into system address space at any given point in
          time.
      
          Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access
          different portions of the media.  BLK-mode, by definition, does not
          support DAX.
      
        BTT:
          This is a library, optionally consumed by either PMEM or BLK, that
          converts a byte-accessible namespace into a disk with atomic sector
          update semantics (prevents sector tearing on crash or power loss).
      
          The sinister aspect of sector tearing is that most applications do
          not know they have a atomic sector dependency.  At least today's
          disk's rarely ever tear sectors and if they do one almost certainly
          gets a CRC error on access.  NVDIMMs will always tear and always
          silently.  Until an application is audited to be robust in the
          presence of sector-tearing the usage of BTT is recommended.

      Add reflink copy over SMB3.11 with new FSCTL_DUPLICATE_EXTENTS · 02b16665
      Steve French authored
       Getting fantastic copy performance with cp --reflink over SMB3.11
       using the new FSCTL_DUPLICATE_EXTENTS.
      
       This FSCTL was added in the SMB3.11 dialect (testing was
       against REFS file system) so have put it as a 3.11 protocol
       specific operation ("vers=3.1.1" on the mount).  Tested at
       the SMB3 plugfest in Redmond.
      
       It depends on the new FS Attribute (BLOCK_REFCOUNTING) which
       is used to advertise support for the ability to do this ioctl
       (if you can support multiple files pointing to the same block
       than this refcounting ability or equivalent is needed to
       support the new reflink-like duplicate extent SMB3 ioctl.

      block: fix bogus EFAULT error from SG_IO ioctl · 2c4cffe8

      Whenever blk_fill_sghdr_rq fails, its errno code is ignored and changed to
      EFAULT.  This can cause very confusing errors:
      
        $ sg_persist -k /dev/sda
        persistent reservation in: pass through os error: Bad address
      
      The fix is trivial, just propagate the return value from

      NVMe: Failed controller initialization fixes · de3eff2b
      Keith Busch authored
      This fixes an infinite device reset loop that may occur on devices that
      fail initialization. If the drive fails to become ready for any reason
      that does not involve an admin command timeout, the probe task should
      assume the drive is unavailable and remove it from the topology. In
      the case an admin command times out during device probing, the driver's
      existing reset action will handle removing the drive.
