    ext4: collapse a single extent tree block into the inode if possible · ecb94f5f
    Theodore Ts'o authored
    If an inode has more than 4 extents, but then later some of the
    extents are merged together, we can optimize the file system by moving
    the extents up into the inode, and discarding the extent tree block.
    This is important, because if there are a large number of inodes with
    an external extent tree blocks where the contents could fit in the
    inode, this can significantly increase the fsck time of the file
    system.
