rb tree nodes are allocated even if a node not online;
the above would change that. Are you saying it is

It is not advisable to allocate since an offline node means that the
structure cannot be allocated on the node where it would be most
beneficial. Typically subsystems allocate the per node data structures
when the node is brought online.

Not that I have any idea what is correct, it just seems odd
that the existing code would do all this allocation if it is not
necessary.

Not sure how the code there works just guessing from other subsystems.
