      proc: Use nd_jump_link in proc_ns_follow_link · db04dc67
      Eric W. Biederman 提交于
      Update proc_ns_follow_link to use nd_jump_link instead of just
      manually updating nd.path.dentry.
      
      This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
      Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.
      
      Sigh it looks like the VFS change to require use of nd_jump_link
      happend while proc_ns_follow_link was baking and since the common case
      of proc_ns_follow_link continued to work without problems the need for
      making this change was overlooked.

      Linus Torvalds 提交于
      Pull btrfs fixes from Chris Mason:
       "These are scattered fixes and one performance improvement.  The
        biggest functional change is in how we throttle metadata changes.  The
        new code bumps our average file creation rate up by ~13% in fs_mark,
        and lowers CPU usage.
      
        Stefan bisected out a regression in our allocation code that made
        balance loop on extents larger than 256MB."
      
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:

      Platform: x86: chromeos_laptop : Add basic platform data for atmel devices · 2ef39204
      Benson Leung 提交于
      Add basic platform data to get the current upstream driver working
      with the 224s touchpad and 1664s touchscreen.
      We will be using NULL config so we will use the settings from the
      devices' NVRAMs.

      Input: atmel_mxt_ts - Support for touchpad variant · 22dfab7f
      Daniel Kurtz 提交于
      This same driver can be used by atmel based touchscreens and touchpads
      (buttonpads). Platform data may specify a device is a touchpad
      using the is_tp flag.
      
      This will cause the driver to perform some touchpad specific
      initializations, such as:
        * register input device name "Atmel maXTouch Touchpad" instead of
        Touchscreen.
        * register BTN_LEFT & BTN_TOOL_* event types.
        * register axis resolution (as a fixed constant, for now)
        * register BUTTONPAD property
        * process GPIO buttons using reportid T19
      
      Input event GPIO mapping is done by the platform data key_map array.
      
      key_map[x] should contain the KEY or BTN code to send when processing
      GPIOx from T19. To specify a GPIO as not an input source, populate
      with KEY_RESERVED, or 0.

      Include <asm/pal.h> so we can get building again.
