      Pull md updates from Neil Brown:
       "More updates that usual this time.  A few have performance impacts
        which hould mostly be positive, but RAID5 (in particular) can be very
        work-load ensitive...  We'll have to wait and see.
      
        Highlights:
      
         - "experimental" code for managing md/raid1 across a cluster using
           DLM.  Code is not ready for general use and triggers a WARNING if
           used.  However it is looking good and mostly done and having in
           mainline will help co-ordinate development.
      
         - RAID5/6 can now batch multiple (4K wide) stripe_heads so as to
           handle a full (chunk wide) stripe as a single unit.
      
         - RAID6 can now perform read-modify-write cycles which should help
           performance on larger arrays: 6 or more devices.
      
         - RAID5/6 stripe cache now grows and shrinks dynamically.  The value
           set is used as a minimum.
      
         - Resync is now allowed to go a little faster than the 'mininum' when
           there is competing IO.  How much faster depends on the speed of the
           devices, so the effective minimum should scale with device speed to
           some extent"

      Linus Torvalds 提交于
      Pull initial ACPI support for arm64 from Will Deacon:
       "This series introduces preliminary ACPI 5.1 support to the arm64
        kernel using the "hardware reduced" profile.  We don't support any
        peripherals yet, so it's fairly limited in scope:
      
         - MEMORY init (UEFI)
      
         - ACPI discovery (RSDP via UEFI)
      
         - CPU init (FADT)
      
         - GIC init (MADT)
      
         - SMP boot (MADT + PSCI)
      
         - ACPI Kconfig options (dependent on EXPERT)
      
        ACPI for arm64 has been in development for a while now and hardware
        has been available that can boot with either FDT or ACPI tables.  This
        has been made possible by both changes to the ACPI spec to cater for
        ARM-based machines (known as "hardware-reduced" in ACPI parlance) but
        also a Linaro-driven effort to get this supported on top of the Linux
        kernel.  This pull request is the result of that work.
      
        These changes allow us to initialise the CPUs, interrupt controller,
        and timers via ACPI tables, with memory information and cmdline coming
        from EFI.  We don't support a hybrid ACPI/FDT scheme.  Of course,
        there is still plenty of work to do (a serial console would be nice!)
        but I expect that to happen on a per-driver basis after this core
        series has been merged.
      
        Anyway, the diff stat here is fairly horrible, but splitting this up
        and merging it via all the different subsystems would have been
        extremely painful.  Instead, we've got all the relevant Acks in place
        and I've not seen anything other than trivial (Kconfig) conflicts in
        -next (for completeness, I've included my resolution below).  Nearly
        half of the insertions fall under Documentation/.
      
        So, we'll see how this goes.  Right now, it all depends on EXPERT and
        I fully expect people to use FDT by default for the immediate future"

       "This update contains:
      
         - RENAME_WHITEOUT support
      
         - conversion of per-cpu superblock accounting to use generic counters
      
         - new inode mmap lock so that we can lock page faults out of
           truncate, hole punch and other direct extent manipulation functions
           to avoid racing mmap writes from causing data corruption
      
         - rework of direct IO submission and completion to solve data
           corruption issue when running concurrent extending DIO writes.
           Also solves problem of running IO completion transactions in
           interrupt context during size extending AIO writes.
      
         - FALLOC_FL_INSERT_RANGE support for inserting holes into a file via
           direct extent manipulation to avoid needing to copy data within the
           file
      
         - attribute block header field overflow fix for 64k block size
           filesystems
      
         - Lots of changes to log messaging to be more informative and concise
           when errors occur.  Also prevent a lot of unnecessary log spamming
           due to cascading failures in error conditions.
      
         - lots of cleanups and bug fixes
      
        One thing of note is the direct IO fixes that we merged last week
        after the window opened.  Even though a little late, they fix a user
        reported data corruption and have been pretty well tested.  I figured

      x86: fix special __probe_kernel_write() tail zeroing case · d869844b
      Linus Torvalds 提交于
      Commit cae2a173 ("x86: clean up/fix 'copy_in_user()' tail zeroing")
      fixed the failure case tail zeroing of one special case of the x86-64
      generic user-copy routine, namely when used for the user-to-user case
      ("copy_in_user()").
      
      But in the process it broke an even more unusual case: using the user
      copy routine for kernel-to-kernel copying.
      
      Now, normally kernel-kernel copies are obviously done using memcpy(),
      but we have a couple of special cases when we use the user-copy
      functions.  One is when we pass a kernel buffer to a regular user-buffer
      routine, using set_fs(KERNEL_DS).  That's a "normal" case, and continued
      to work fine, because it never takes any faults (with the possible
      exception of a silent and successful vmalloc fault).
      
      But Jan Beulich pointed out another, very unusual, special case: when we
      use the user-copy routines not because it's a path that expects a user
      pointer, but for a couple of ftrace/kgdb cases that want to do a kernel
      copy, but do so using "unsafe" buffers, and use the user-copy routine to
      gracefully handle faults.  IOW, for probe_kernel_write().
      
      And that broke for the case of a faulting kernel destination, because we
      saw the kernel destination and wanted to try to clear the tail of the
      buffer.  Which doesn't work, since that's what faults.
      
      This only triggers for things like kgdb and ftrace users (eg trying
      setting a breakpoint on read-only memory), but it's definitely a bug.
      The fix is to not compare against the kernel address start (TASK_SIZE),
      but instead use the same limits "access_ok()" uses.
