Subject: [PATCHv3 03/10] scsi: use request helper to get integrity segments
Date: Wed, 4 Sep 2024 08:25:58 -0700 [thread overview]
Message-ID: <20240904152605.4055570-4-kbusch@meta.com> (raw)
In-Reply-To: <20240904152605.4055570-1-kbusch@meta.com>
From: Keith Busch <kbusch@kernel.org>
The request tracks the integrity segments already, so no need to recount
the segements again.
