Subject: [PATCH 1/8] btrfstune: Remove fs_info arg from change_device_uuid
Date: Thu, 11 Oct 2018 18:03:57 +0300	[thread overview]
Message-ID: <1539270244-27076-2-git-send-email-nborisov@suse.com> (raw)
In-Reply-To: <1539270244-27076-1-git-send-email-nborisov@suse.com>

This function already takes an extent buffer that contains a reference
to the fs_info. Use that and reduce argument count. No functional
changes.
