generic radix trees
Very simple radix tree implementation that supports storing arbitrary size entries, up to PAGE_SIZE - upcoming patches will convert existing flex_array users to genradixes. The new genradix code has a much simpler API and implementation, and doesn't have a hard limit on the number of elements like flex_array does.
