Subject: [PATCH 2/2] hw/block/nvme: fix lbaf formats initialization
Date: Fri, 16 Apr 2021 12:52:34 +0530	[thread overview]
Message-ID: <20210416072234.25732-2-anaidu.gollu@samsung.com> (raw)
In-Reply-To: <20210416072234.25732-1-anaidu.gollu@samsung.com>

Currently LBAF formats are being intialized based on metadata
size if and only if nvme-ns "ms" parameter is non-zero value.
Since FormatNVM command being supported device parameter "ms"
may not be the criteria to initialize the supported LBAFs.
