From d17d51a92a3a1c1cce1e646c38fe52ca99406cf9 Mon Sep 17 00:00:00 2001 From: Kazuhito Hagio Date: Fri, 7 Jul 2023 15:17:18 +0900 Subject: [PATCH 2/4] Exclude zero entries from do_maple_tree() return value While the return value of do_radix_tree() and do_xarray() does not contain NULL entries, do_maple_tree()'s one contains NULL entries. Make this behavior consistent with the previous tree functions to make replacement easier, especially for the following patch.
