Subject: [PATCH 04/44] btrfs: export and use btrfs_read_tree_root
Date: Fri,  6 Dec 2019 09:44:58 -0500	[thread overview]
Message-ID: <20191206144538.168112-5-josef@toxicpanda.com> (raw)
In-Reply-To: <20191206144538.168112-1-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.
