I wrote tree route setup code. Tree route is set up though a proc file system /proc/setup_treeroute.

$ echo 1 20 > /proc/setup_treeroute the first arg is a flag whether the current node is active or not. set 1 if the node is active, otherwise 0 the second arg is the total number of active nodes in partition

I've tested several combinations on SMP mode(only smp is supported) I haven't seen any problem so far.
