      Revert "sched: Update_cfs_shares at period edge" · 17bc14b7
      Linus Torvalds 提交于
      This reverts commit f269ae04.
      
      It turns out it causes a very noticeable interactivity regression with
      CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
      terminal window, while scrolling in a browser - the autogrouping means
      that the two end up in separate cgroups, and the browser should be
      smooth as silk despite the high load).
      
      Says Paul Turner:
       "It seems that the update-throttling on the wake-side is reducing the
        interactive tasks' ability to preempt.  While I suspect the right
        longer term answer here is force these updates only in the
        cross-cgroup case; this is less trivial.  For this release I believe
        the right answer is either going to be a revert or restore the updates
        on the enqueue-side."

      Merge emailed autofs cleanup/fix patches from Ian Kent
      
      * autofs:
        autofs4 - use simple_empty() for empty directory check

      autofs4 - use simple_empty() for empty directory check · 0259cb02
      Ian Kent 提交于
      For direct (and offset) mounts, if an automounted mount is manually
      umounted the trigger mount dentry can appear non-empty causing it to
      not trigger mounts. This can also happen if there is a file handle
      leak in a user space automounting application.
      
      This happens because, when a ioctl control file handle is opened
      on the mount, a cursor dentry is created which causes list_empty()
      to see the dentry as non-empty. Since there is a case where listing
      the directory of these dentrys is needed, the use of dcache_dir_*()
      functions for .open() and .release() is needed.
      
      Consequently simple_empty() must be used instead of list_empty()
      when checking for an empty directory.

      autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount · f55fb0c2
      Ian Kent 提交于
      The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire
      for autofs rootless multi-mount dentrys to prevent unnecessary calls
      to ->d_automount().
      
      Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed()
      is always called so the check can be done in ->d_manage() without the
      need to change the flag. This still avoids unnecessary calls to
      ->d_automount(), adds negligible overhead and eliminates a seriously
      ugly check in the expire code.

      Merge misc VM changes from Andrew Morton:
       "The rest of most-of-MM.  The other MM bits await a slab merge.
      
        This patch includes the addition of a huge zero_page.  Not a
        performance boost but it an save large amounts of physical memory in
        some situations.
      
        Also a bunch of Fujitsu engineers are working on memory hotplug.
        Which, as it turns out, was badly broken.  About half of their patches
        are included here; the remainder are 3.8 material."
      
      However, this merge disables CONFIG_MOVABLE_NODE, which was totally
      broken.  We don't add new features with "default y", nor do we add
      Kconfig questions that are incomprehensible to most people without any
      help text.  Does the feature even make sense without compaction or
      memory hotplug?

      YOSHIFUJI Hideaki / 吉藤英明 提交于
      If a natural number n exists where 2 + data_len <= 8n < 2 + data_len + pad,
      post padding is not initialized correctly.
      
      (Un)fortunately, the only type that requires pad is Infiniband,
      whose pad is 2 and data_len is 20, and this logical error has not
      become obvious, but it is better to fix.

      above correctly.
