Actually, I believe the ranges you need to track are non-overlapping, correct ?

If that is the case, a simple rbtree, sorted by start-of-range
address, would work best.

John,

JFYI, if you want to try a possible rbtree-based implementation, as
suggested by Michel you could try this one:
https://github.com/arighi/kinterval

This implementation supports insertion, deletion and transparent merging
of adjacent ranges, as well as splitting ranges when chunks removed or
different chunk types are added in the middle of an existing range; so
if I'm not wrong probably you should be able to use this code as is,
without any modification.

If you decide to go this way and/or need help to use it in your patch
set just let me know.
