        Main new things this cycle is:
      
         - Driver changes to expose the lightbar to users.  With this, you can
           make your own blinkenlights on Chromebook Pixels.
      
         - Changes in the way that the atmel_mxt trackpads are probed.  The
           laptop driver is trying to be smart and not instantiate the devices
           that don't answer to probe.  For the trackpad that can come up in
           two modes (bootloader or regular), this gets complicated since the
           driver already knows how to handle the two modes including the
           actual addresses used.  So now the laptop driver needs to know more
           too, instantiating the regular address even if the bootloader one
           is the probe that passed.

      platform/chrome: chromeos_laptop - instantiate Atmel at primary address · 96cba9b0
      Dmitry Torokhov authored
      The new Atmel MXT driver expects i2c client's address contain the
      primary (main address) of the chip, and calculates the expected
      bootloader address form the primary address. Unfortunately chrome_laptop
      does probe the devices and if touchpad (or touchscreen, or both) comes
      up in bootloader mode the i2c device gets instantiated with the
      bootloader address which confuses the driver.
      
      To work around this issue let's probe the primary address first. If the
      device is not detected at the primary address we'll probe alternative
      addresses as "dummy" devices. If any of them are found, destroy the
      dummy client and instantiate client with proper name at primary address
      still.

      RCU pathwalk breakage when running into a symlink overmounting something · 3cab989a
      Al Viro authored
      Calling unlazy_walk() in walk_component() and do_last() when we find
      a symlink that needs to be followed doesn't acquire a reference to vfsmount.
      That's fine when the symlink is on the same vfsmount as the parent directory
      (which is almost always the case), but it's not always true - one _can_
      manage to bind a symlink on top of something.  And in such cases we end up
      with excessive mntput().

      direct-io: only inc/dec inode->i_dio_count for file systems · fe0f07d0
      Jens Axboe authored
      do_blockdev_direct_IO() increments and decrements the inode
      ->i_dio_count for each IO operation. It does this to protect against
      truncate of a file. Block devices don't need this sort of protection.
      
      For a capable multiqueue setup, this atomic int is the only shared
      state between applications accessing the device for O_DIRECT, and it
      presents a scaling wall for that. In my testing, as much as 30% of
      system time is spent incrementing and decrementing this value. A mixed
      read/write workload improved from ~2.5M IOPS to ~9.6M IOPS, with
      better latencies too. Before:
      
      clat percentiles (usec):

      improvements:
      
      https://lkml.org/lkml/2015/4/3/557
      
      The more applications accessing the device, the worse it gets.
      
      Add a new direct-io flags, DIO_SKIP_DIO_COUNT, which tells
      do_blockdev_direct_IO() that it need not worry about incrementing
      or decrementing the inode i_dio_count for this caller.

      Btrfs: prevent list corruption during free space cache processing · a3bdccc4
      Chris Mason authored
      __btrfs_write_out_cache is holding the ctl->tree_lock while it prepares
      a list of bitmaps to record in the free space cache.  It was dropping

      This changes things to hold the lock the whole time, and also makes sure
      we hold the lock during enospc cleanup.

      toshiba_acpi: Do not register vendor backlight when acpi_video bl is available · 358d6a2c
      Hans de Goede authored
      commit a39f46df ("toshiba_acpi: Fix regression caused by backlight extra
      check code") causes the backlight to no longer work on the Toshiba Z30,
      reverting that commit fixes this but restores the original issue fixed
      by that commit.
      
      Looking at the toshiba_acpi backlight code for a fix for this I noticed that
      the toshiba code is the only code under platform/x86 which unconditionally
      registers a vendor acpi backlight interface, without checking for acpi_video
      backlight support first.
      
      This commit adds the necessary checks bringing toshiba_acpi in line with the
      other drivers, and fixing the Z30 regression without needing to revert the
      commit causing it.
      
      Chances are that there will be some Toshiba models which have a non working
      acpi-video implementation while the toshiba vendor backlight interface does
      work, this commit adds an empty dmi_id table where such systems can be added,
      this is identical to how other drivers handle such systems.
