Subject: [PATCH 13/27] block: add a bdev_fua helper
Date: Fri, 15 Apr 2022 06:52:44 +0200	[thread overview]
Message-ID: <20220415045258.199825-14-hch@lst.de> (raw)
In-Reply-To: <20220415045258.199825-1-hch@lst.de>

Add a helper to check the FUA flag based on the block_device instead of
having to poke into the block layer internal request_queue.

Subject: [PATCH 13/27] block: add a bdev_fua helper
Date: Fri, 15 Apr 2022 06:52:44 +0200	[thread overview]
Message-ID: <20220415045258.199825-14-hch@lst.de> (raw)
In-Reply-To: <20220415045258.199825-1-hch@lst.de>

Add a helper to check the FUA flag based on the block_device instead of
having to poke into the block layer internal request_queue.
