Subject: [PATCH 3/5] btrfs: Sink total_data parameter in setup_items_for_insert
Date: Tue,  1 Sep 2020 17:39:59 +0300	[thread overview]
Message-ID: <20200901144001.4265-4-nborisov@suse.com> (raw)
In-Reply-To: <20200901144001.4265-1-nborisov@suse.com>

That parameter can easily be derived based on the "data_size" and "nr"
parameters exploit this fact to simply the function's signature. No
functional changes.
