Subject: [PATCH V3 8/9] nvmet: add zns bdev config support
Date: Mon, 30 Nov 2020 20:14:15 -0800	[thread overview]
Message-ID: <20201201041416.16293-9-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20201201041416.16293-1-chaitanya.kulkarni@wdc.com>

For zbd based bdev backend we need to override the ns->blksize_shift
with the physical block size instead of using the logical block size
so that SMR drives will not result in an error.

Update the nvmet_bdev_ns_enable() to reflect that.
