[PATCH v6 23/25] files_log_ref_write: new function

From
Michael Haggerty <mhagger@alum.mit.edu>
Date
Nov 3, 2015, 07:40 UTC
Message-ID
<5b305c7ef25dc53e5b6ee11169c16fdbeda4ad86.1446534991.git.mhagger@alum.mit.edu>
In-Reply-To
<cover.1446534991.git.mhagger@alum.mit.edu>
From: David Turner <dturner@twopensource.com>

Because HEAD and stash are per-worktree, every refs backend needs to go through the files backend to write these refs.

So create a new function, files_log_ref_write, and add it to refs/refs-internal.h. Later, we will use this to handle reflog updates for per-worktree symbolic refs (HEAD).
