Subject: [PATCH v5 02/11] block: introduce bio zone helpers
Date: Wed, 26 May 2021 06:24:52 +0900	[thread overview]
Message-ID: <20210525212501.226888-3-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20210525212501.226888-1-damien.lemoal@wdc.com>

Introduce the helper functions bio_zone_no() and bio_zone_is_seq().
Both are the BIO counterparts of the request helpers blk_rq_zone_no()
and blk_rq_zone_is_seq(), respectively returning the number of the
target zone of a bio and true if the BIO target zone is sequential.
