Subject: [PATCH v2 03/28] block: Introduce blk_zone_update_request_bio()
Date: Mon, 25 Mar 2024 13:44:27 +0900	[thread overview]
Message-ID: <20240325044452.3125418-4-dlemoal@kernel.org> (raw)
In-Reply-To: <20240325044452.3125418-1-dlemoal@kernel.org>

On completion of a zone append request, the request sector indicates the
location of the written data. This value must be returned to the user
through the BIO iter sector. This is done in 2 places: in
blk_complete_request() and in blk_update_request(). Introduce the inline
helper function blk_zone_update_request_bio() to avoid duplicating
this BIO update for zone append requests, and to compile out this
helper call when CONFIG_BLK_DEV_ZONED is not enabled.

Signed-off-by: Damien Le Moal <dlemoal@kernel.org>
