    xfs: consolidate leaf/node states in xfs_attr_set_iter · 251b29c8
    Dave Chinner authored
    The operations performed from XFS_DAS_FOUND_LBLK through to
    XFS_DAS_RM_LBLK are now identical to XFS_DAS_FOUND_NBLK through to
    XFS_DAS_RM_NBLK. We can collapse these down into a single set of
    code.
    
    To do this, define the states that leaf and node run through as
    separate sets of sequential states. Then as we move to the next
    state, we can use increments rather than specific state assignments
    to move through the states. This means the state progression is set
    by the initial state that enters the series and we don't need to
    duplicate the code anymore.
    
    At the exit point of the series we need to select the correct leaf
    or node state, but that can also be done by state increment rather
    than assignment.
