From ee550abcce86e27c0be3593a4c9af4dc7322039a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 3 Jul 2023 02:44:21 -0400 Subject: [PATCH] merge-tree: mark unused parameter in traverse callback Our threeway_callback() does not bother to look at its "n" parameter. It is static in this file and used only by trivial_merge_trees(), which always passes 3 trees (hence the name "threeway"). It also does not look at "dirmask". This is OK, as it handles directories specifically by looking at the mode bits. Other traverse_info callbacks need these, so we can't get drop them from the interface. But let's annotate these ones to avoid complaints from -Wunused-parameter.
