      shmem: Fix link error if huge pages support is disabled · 4620a06e
      Geert Uytterhoeven authored
      If CONFIG_TRANSPARENT_HUGE_PAGECACHE=n, HPAGE_PMD_NR evaluates to
      BUILD_BUG_ON(), and may cause (e.g. with gcc 4.12):
      
          mm/built-in.o: In function `shmem_alloc_hugepage':
          shmem.c:(.text+0x17570): undefined reference to `__compiletime_assert_1365'
      
      To fix this, move the assignment to hindex after the check for huge
      pages support.

      drm: i915: fix build when DEBUG_FS is disabled · 25fd91dc
      Linus Torvalds authored
      This clearly had never gotten tested, probably because you need a fairly
      minimal configuration in order to disable DEBUG_FS (several other
      options select it).
      
      The dummy inline functions that were used for the no-DEBUG_FS case were
      missing the argument names in the declarations.
      
      Fixes: 1dac891c ("drm/i915: Register debugfs interface last")

      fs/proc: Add compiler check for -Wno-override-init to support gcc < 4.2 · 4b2e0162
      Geert Uytterhoeven authored
      With gcc < 4.2 (e.g. 4.1.2):

          cc1: error: unrecognized command line option "-Wno-override-init"

      Pull orangefs update from Martin Brandenburg:
       "Kernel side caching and executable bugfix
      
        This allows OrangeFS to utilize the dcache and adds an in kernel
        attribute cache.  We previously used the user side client for this
        purpose.
      
        We see a modest performance increase on small file operations.  For
        example, without the cache, compiling coreutils takes about 17
        minutes.  With the patch and a 50 millisecond timeout for
        dcache_timeout_msecs and getattr_timeout_msecs (the default),
        compiling coreutils takes about 6 minutes 20 seconds.  On the same
        hardware, compiling coreutils on an xfs filesystem takes 90 seconds.
        We see similar improvements with mdtest and a test involving writing,
        reading, and deleting a large number of small files.
      
        Interested parties can review more data at the following URL.
      
          https://docs.google.com/spreadsheets/d/1v4aUeppKexIbRMz_Yn9k4eaM3uy2KCaPoe_93YKWOtA/pubhtml
      
        The eventual goal of this is to allow getdents to turn into a
        readdirplus to the OrangeFS server.  The cache will be filled then,
        which should provide a performance benefit to the common case of
        readdir followed by getattr on each entry (i.e.  ls -l).
      
        This also fixes a bug.  When orangefs_inode_permission was added, it
        did not collect i_size from the OrangeFS server, since this presses an
        unnecessary load on the OrangeFS server.  However, it left a case
        where i_size is never initialized.  Then running an executable could
        fail.
      
        With this patch, size is always collected to be inserted into the
        cache.  Thus the bug disappears.  If this patch is not accepted during
        this merge window, we will send a one-line band-aid for this bug
        instead"
