From 02c3c59e62a30771d209a171edfc75a4d7387ebe Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 19 Aug 2022 06:08:46 -0400 Subject: hashmap: mark unused callback parameters Hashmap comparison functions must conform to a particular callback interface, but many don't use all of their parameters. Especially the void cmp_data pointer, but some do not use keydata either (because they can easily form a full struct to pass when doing lookups). Let's mark these to make -Wunused-parameter happy.
