Basically yes, although it was the documentation you added to the
latched seqlock code in particular.
I haven't checked the users of your rb-tree code to see how large and
frequently read the trees are, but if a read is expensive, then avoiding
retries by incrementing the seqlock twice per update starts to become
interesting.
