Subject: [PATCH 14/15] btrfs-progs: mkfs: create the gc tree at mkfs time
Date: Wed, 15 Dec 2021 15:14:52 -0500 [thread overview]
Message-ID: <0fe935e76e614a58ff9f0cda106a828ef5742229.1639598612.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1639598612.git.josef@toxicpanda.com>
Now that progs has the support to read this tree, create it at global
root creation time. We don't need this root to bootstrap the file
system so just create it at this later point.
