Subject: [PATCH 09/14] btrfs: use btrfs_read_node_slot in qgroup_trace_new_subtree_blocks
Date: Fri, 30 Oct 2020 17:03:01 -0400 [thread overview]
Message-ID: <35706903f3ff92e0e2a44b9d2c468149b85380bd.1604091530.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1604091530.git.josef@toxicpanda.com>
We're open-coding btrfs_read_node_slot() here, replace with the helper.
