Subject: [PATCH 05/14] btrfs: use btrfs_read_node_slot in do_relocation
Date: Fri, 30 Oct 2020 17:02:57 -0400	[thread overview]
Message-ID: <ecaac3d0674a2ba8ec0427ce95d8e52eb38298c6.1604091530.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1604091530.git.josef@toxicpanda.com>

We're open coding btrfs_read_node_slot in do_relocation, replace this
with the proper helper.
