The quilt patch titled Subject: maple_tree: simplify mas_push_node() has been removed from the -mm tree. Its filename was maple_tree-simplify-mas_push_node.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: maple_tree: simplify mas_push_node() Date: Tue, 15 Oct 2024 12:07:46 +0000 When count is not 0, we know head is valid. So we can put the assignment in if (count) instead of checking the head pointer again. Also count represents current total, we can assign the new total by increasing the count by one.
