    Btrfs: sort references by byte number during btrfs_inc_ref · b7a9f29f
    Chris Mason authored
    When a block goes through cow, we update the reference counts of
    everything that block points to.  The internal pointers of the block
    can be in just about any order, and it is likely to have clusters of
    things that are close together and clusters of things that are not.
    
    To help reduce the seeks that come with updating all of these reference
    counts, sort them by byte number before actual updates are done.
