From c41ad98bebb8f4f0335b3c50dbb7583a6149dce4 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Fri, 7 Aug 2020 09:32:35 -0700 Subject: [PATCH] nvme: skip noiob for zoned devices 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.
