Subject: [PATCH 23/23] reflink: test reflink+cow+enospc all at the same time
Date: Mon, 08 Feb 2016 17:14:14 -0800 [thread overview]
Message-ID: <20160209011414.23099.38917.stgit@birch.djwong.org> (raw)
In-Reply-To: <20160209011145.23099.95354.stgit@birch.djwong.org>
Set up an impossibly small filesystem and try to reflink and rewrite a
file on it to see what happens when we ENOSPC. Basically
generic/16[67] but with a constrained fs size.
