Thanks for your patch. Unfortunately, this entire function is scheduled for deletion, so I won't be applying it. If you're interested in the radix tree, I'd recommend looking at its replacement, the XArray. The current version is at http://git.infradead.org/users/willy/linux-dax.git/shortlog/refs/heads/xarray but I'll be pushing another version out in the next few days.
