From 0c064d907b5d96cb4f68c9f1f3214b115d43436e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Tue, 4 Apr 2017 17:21:20 +0700 Subject: [PATCH] refs.c: make submodule ref store hashmap generic MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This removes the "submodule" from submodule_hash_entry and other function names. The goal is to reuse the same code and data structure for other ref store types. The first one is worktree ref stores.
