Subject: [PATCHv3 12/12] dmapool: create/destroy cleanup
Date: Tue, 3 Jan 2023 11:15:51 -0800 [thread overview]
Message-ID: <20230103191551.3254778-13-kbusch@meta.com> (raw)
In-Reply-To: <20230103191551.3254778-1-kbusch@meta.com>
From: Keith Busch <kbusch@kernel.org>
Set the 'empty' bool directly from the result of the function that
determines its value instead of adding indirection logic.
