Subject: [PATCH 12/27] block: add a bdev_write_cache helper
Date: Fri, 15 Apr 2022 06:52:43 +0200	[thread overview]
Message-ID: <20220415045258.199825-13-hch@lst.de> (raw)
In-Reply-To: <20220415045258.199825-1-hch@lst.de>

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

Subject: [dm-devel] [PATCH 12/27] block: add a bdev_write_cache helper
Date: Fri, 15 Apr 2022 06:52:43 +0200	[thread overview]
Message-ID: <20220415045258.199825-13-hch@lst.de> (raw)
In-Reply-To: <20220415045258.199825-1-hch@lst.de>

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

Signed-off-by: Christoph Hellwig <hch@lst.de>
Reviewed-by: Martin K. Petersen <martin.petersen@oracle.com>
