Subject: [PATCH AUTOSEL 5.8 11/42] nvme: skip noiob for zoned devices
Date: Mon, 31 Aug 2020 11:29:03 -0400 [thread overview]
Message-ID: <20200831152934.1023912-11-sashal@kernel.org> (raw)
In-Reply-To: <20200831152934.1023912-1-sashal@kernel.org>
From: Keith Busch <kbusch@kernel.org>
[ Upstream commit c41ad98bebb8f4f0335b3c50dbb7583a6149dce4 ]
Zoned block devices reuse the chunk_sectors queue limit to define zone
boundaries. If a such a device happens to also report an optimal
boundary, do not use that to define the chunk_sectors as that may
intermittently interfere with io splitting and zone size queries.
