Subject: [PATCH v3 1/3] scsi: ufs: core: add wb buffer resize related attr_idn
Date: Mon, 11 Sep 2023 13:57:06 +0800	[thread overview]
Message-ID: <20230911055810.879-2-luhongfei@vivo.com> (raw)
In-Reply-To: <20230911055810.879-1-luhongfei@vivo.com>

As we know, the ballot for resizing the WriteBooster buffer has been
approved.

UFS will support the WB buffer resize function, and UFS driver can
add definitions for attr_idn related to this function to support
this feature.
