      ext4: Clean up s_dirt handling · a0375156

      We don't need to set s_dirt in most of the ext4 code when journaling
      is enabled.  In ext3/4 some of the summary statistics for # of free
      inodes, blocks, and directories are calculated from the per-block
      group statistics when the file system is mounted or unmounted.  As a
      result the superblock doesn't have to be updated, either via the
      journal or by setting s_dirt.  There are a few exceptions, most
      notably when resizing the file system, where the superblock needs to
      be modified --- and in that case it should be done as a journalled
      operation if possible, and s_dirt set only in no-journal mode.
      
      This patch will optimize out some unneeded disk writes when using ext4
      with a journal.
