Subject: [PATCH 28/40] btrfs: relocation: Open-code read_fs_root() for handle_indirect_tree_backref()
Date: Mon, 23 Mar 2020 18:24:04 +0800 [thread overview]
Message-ID: <20200323102416.112862-29-wqu@suse.com> (raw)
In-Reply-To: <20200323102416.112862-1-wqu@suse.com>
The backref code is going to be moved to backref.c, and read_fs_root()
is just a simple wrapper, open-code it to prepare to the incoming code
move.
