    Zheng Liu authored
    This commit refines the extent status tree code.
    
    1) A prefix 'es_' is added to to the extent status tree structure
    members.
    
    2) Refactored es_remove_extent() so that __es_remove_extent() can be
    used by es_insert_extent() to remove the old extent entry(-ies) before
    inserting a new one.
    
    3) Rename extent_status_end() to ext4_es_end()
    
    4) ext4_es_can_be_merged() is define to check whether two extents can
    be merged or not.
    
    5) Update and clarified comments.
