Subject: [PATCH 04/43] btrfs: export and use btrfs_read_tree_root
Date: Fri, 17 Jan 2020 08:47:19 -0500	[thread overview]
Message-ID: <20200117134758.41494-5-josef@toxicpanda.com> (raw)
In-Reply-To: <20200117134758.41494-1-josef@toxicpanda.com>

log-tree uses btrfs_read_fs_root to load its log, but this just calls
btrfs_read_tree_root.  We don't save the log roots in our root cache, so
just export this helper and use it in the logging code.
