Subject: [PATCH v11 01/10] block: provide fallbacks for blk_queue_zone_is_seq and blk_queue_zone_no
Date: Tue, 12 May 2020 17:55:45 +0900 [thread overview]
Message-ID: <20200512085554.26366-2-johannes.thumshirn@wdc.com> (raw)
In-Reply-To: <20200512085554.26366-1-johannes.thumshirn@wdc.com>
blk_queue_zone_is_seq() and blk_queue_zone_no() have not been called with
CONFIG_BLK_DEV_ZONED disabled until now.
The introduction of REQ_OP_ZONE_APPEND will change this, so we need to
provide noop fallbacks for the !CONFIG_BLK_DEV_ZONED case.
