+It would be easier to read reiserfs_lb_balance() if each of these summary
+lines was a separate procedure rather than being inlined. I think
+that there are many passages here and in reiserfs_lb_balance_delete() in
+which two calls to one procedure can replace two passages, and it
+might save cache space and improve software maintenance costs to do so.
+
+Vladimir made the perceptive comment that we should offload most of
+the decision making in this function into reiserfs_fix_nodes/check_balance,
+and then create some sort of structure in tb that says what actions should
+be performed by reiserfs_tb_balance.

+
+ if we shift leaves then we shift as much as we can: this is a deliberate policy of extremism in
+ node packing which results in higher average utilization after repeated random balance
+ operations at the cost of more memory copies and more balancing as a result of small insertions
+ to full nodes.
+
+ if we shift internal nodes we try to evenly balance the node utilization, with consequent less
+ balancing at the cost of lower utilization.
+
+ one could argue that the policy for directories in leaves should be that of internal nodes, but
+ we will wait until another day to evaluate this.... It would be nice to someday measure and
+ prove these assumptions as to what is optimal....

- we only delete L if we are deleting two nodes, if we delete only one node we delete S
-
- if we shift leaves then we shift as much as we can: this is a deliberate policy of extremism in
- node packing which results in higher average utilization after repeated random balance
- operations at the cost of more memory copies and more balancing as a result of small insertions
- to full nodes.
-
- if we shift internal nodes we try to evenly balance the node utilization, with consequent less
- balancing at the cost of lower utilization.
-
- one could argue that the policy for directories in leaves should be that of internal nodes, but
- we will wait until another day to evaluate this.... It would be nice to someday measure and
- prove these assumptions as to what is optimal....
