I realise that radix-tree.c isn't a trivial bit of code so I don't
expect reviews to be forthcoming, but if anyone had some spare time
to glance over it that would be great.
I went over this a few times and didn't find any obvious
problems with the RCU aspect of this.
Thanks!
Is my given detail of the implementation clear? Sufficient? Would
diagrams be helpful?
If I were to suggest an ascii diagram for a comment, it would be
one which would show the height invariant this patch takes advantage
of.
I'll see if I can make something reasonably descriptive. And possibly
another diagram to show the node insertion concurrency cases vs lookup.
These things are the main concepts to understand, so I agree diagrams
might be helpful.
