      ext4: fix dir_nlink behaviour · c7414892
      Andreas Dilger authored
      The dir_nlink feature has been enabled by default for new ext4
      filesystems since e2fsprogs-1.41 in 2008, and was automatically
      enabled by the kernel for older ext4 filesystems since the
      dir_nlink feature was added with ext4 in kernel 2.6.28+ when
      the subdirectory count exceeded EXT4_LINK_MAX-1.
      
      Automatically adding the file system features such as dir_nlink is
      generally frowned upon, since it could cause the file system to not be
      mountable on older kernel, thus preventing the administrator from
      rolling back to an older kernel if necessary.
      
      In this case, the administrator might also want to disable the feature
      because glibc's fts_read() function does not correctly optimize
      directory traversal for directories that use st_nlinks field of 1 to
      indicate that the number of links in the directory are not tracked by
      the file system, and could fail to traverse the full directory
      hierarchy.  Fortunately, in the past ten years very few users have
      complained about incomplete file system traversal by glibc's
      fts_read().
      
      This commit also changes ext4_inc_count() to allow i_nlinks to reach
      the full EXT4_LINK_MAX links on the parent directory (including "."
      and "..") before changing i_links_count to be 1.

      ext4: silence array overflow warning · 381cebfe
      Dan Carpenter authored
      I get a static checker warning:
      
          fs/ext4/ext4.h:3091 ext4_set_de_type()
          error: buffer overflow 'ext4_type_by_mode' 15 <= 15
      
      It seems unlikely that we would hit this read overflow in real life, but
      it's also simple enough to make the array 16 bytes instead of 15.

      ext4: fix SEEK_HOLE/SEEK_DATA for blocksize < pagesize · fcf5ea10
      Jan Kara authored
      ext4_find_unwritten_pgoff() does not properly handle a situation when
      starting index is in the middle of a page and blocksize < pagesize. The
      following command shows the bug on filesystem with 1k blocksize:
      
        xfs_io -f -c "falloc 0 4k" \
                  -c "pwrite 1k 1k" \
                  -c "pwrite 3k 1k" \
                  -c "seek -a -r 0" foo
      
      In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
      SEEK_DATA) will return the correct result.
      
      Fix the problem by neglecting buffers in a page before starting offset.

      platform/x86: intel-vbtn: match power button on press rather than release · 946da699
      Mario Limonciello authored
      This fixes a problem where the system gets stuck in a loop
      unable to wakeup via power button in s2idle.
      
      The problem happens because:
       - press power button:
         - system emits 0xc0 (power press), event ignored
         - system emits 0xc1 (power release), event processed,
           emited as KEY_POWER
         - set wakeup_mode to true
         - system goes to s2idle
       - press power button
         - system emits 0xc0 (power press), wakeup_mode is true,
           system wakes
         - system emits 0xc1 (power release), event processed,
           emited as KEY_POWER
         - system goes to s2idle again
      
      To avoid this situation, process the presses (which matches what
      intel-hid does too).

        Visually, the images look the same, but the file size is now a lot
        smaller than before, and they don't use some XML tags that would cause
        them to be badly parsed by some ImageMagick versions, or to require a
        lot of memory by TeTex, with would break PDF output on some

       "A handful of critical fixes for changes introduce this merge window.
      
         - The TI sci_clk_get() API was pretty broken and nobody noticed.
      
         - There were some CPUfreq crashes on C.H.I.P devices because we
           failed to propagate rates up the clk tree.
      
         - Also, the Intel Atom PMC clk driver needs to mark a clk critical if
           the firmware has it enabled already so that audio doesn't get
           killed on Baytrail.
      
         - Gemini devices have a dead serial console because the reset control
           usage in the serial driver assume one method of reset that gemini
           doesn't support (this will be fixed in the next version in the
           reset framework so this is the small fix for -rc series).
