Subject: [PATCH v3 2/5] list-objects: refactor to process_tree_contents
Date: Mon, 13 Aug 2018 11:14:29 -0700	[thread overview]
Message-ID: <feb7ea58228df4bb777ee96651389000e804f9fa.1534183648.git.matvore@google.com> (raw)
In-Reply-To: <cover.1534183648.git.matvore@google.com>

This will be used in a follow-up patch to reduce indentation needed when
invoking the logic conditionally. i.e. rather than:

if (foo) {
	while (...) {
		/* this is very indented */
	}
}

we will have:

if (foo)
	process_tree_contents(...);
