Subject: [PATCH v2 06/18] get_ref_dir(): take the containing directory as argument
Date: Fri, 27 Apr 2012 00:26:55 +0200 [thread overview]
Message-ID: <1335479227-7877-7-git-send-email-mhagger@alum.mit.edu> (raw)
In-Reply-To: <1335479227-7877-1-git-send-email-mhagger@alum.mit.edu>
From: Michael Haggerty <mhagger@alum.mit.edu>
Previously, the "dir" argument to get_ref_dir() was a pointer to the
top-level ref_dir. Change the function to expect a pointer to the
ref_dir corresponding to dirname. This allows entries to be added
directly to dir, without having to recurse through the reference trie
each time (i.e., we can use add_entry_to_dir() instead of add_ref()).
