    Btrfs: optimize set extent bit · 40431d6c
    Chris Mason authored
    The Btrfs set_extent_bit call currently searches the rbtree
    every time it needs to find more extent_state objects to fill
    the requested operation.
    
    This adds a simple test with rb_next to see if the next object
    in the tree was adjacent to the one we just found.  If so,
    we skip the search and just use the next object.
