Future patches will need something like the - meanwhile removed - radix_tree_for_each_contig macro. Since general direction is to use xarray as replacement for radix_tree and IDR, instead of re-introducing or open coding the removed macro, with this series we switch over to xarray API. Based on xarray a future patch easily can implement an analog to radix_tree_for_each_contig.
