Thanks for the links, Randy, I hadn't thought of those at all.

This one just tests that radix_tree_preload() goes deep enough:
not affected by the little change I've made.

This should still be as relevant as it was before, but I notice its
radix_tree.c is almost identical to the source currently in the kernel
tree, so I ought at the least to keep it in synch.

Whether there's anything suitable for testing here in the changes that
I've made, I'll have to look into later.
