Subject: [PATCH 2/7] btrfs: block-group: use btrfs_for_each_slot in find_first_block_group
Date: Tue, 24 Aug 2021 14:06:53 -0300 [thread overview]
Message-ID: <20210824170658.12567-3-mpdesouza@suse.com> (raw)
In-Reply-To: <20210824170658.12567-1-mpdesouza@suse.com>
The function can be simplified by using the iterator like macro.
No functional changes.
