Subject: [PATCH v3 01/10] block: provide fallbacks for blk_queue_zone_is_seq and blk_queue_zone_no
Date: Sat, 28 Mar 2020 01:50:03 +0900	[thread overview]
Message-ID: <20200327165012.34443-2-johannes.thumshirn@wdc.com> (raw)
In-Reply-To: <20200327165012.34443-1-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.
