Subject: [PATCH 2/4] btrfs: tests: move testing members of struct btrfs_root to the end
Date: Mon, 10 Sep 2018 19:22:26 +0200 [thread overview]
Message-ID: <f8b15d6ea41fc91c7e8608352cd242722c4c1b3b.1536599879.git.dsterba@suse.com> (raw)
In-Reply-To: <cover.1536599879.git.dsterba@suse.com>
The data used only for tests are better placed at the end of the
structure so that they don't change the structure layout. All new
members of btrfs_root should be placed before.
