From: Keith Busch <kbusch@xxxxxxxxxx> [ 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.
