Subject: Re: [PATCH v15 00/19] Improve write performance for zoned UFS devices

As this keeps getting reposted:
I still think it is a very bad idea to add this amount of complexity to
the SCSI code, for a model that can't work for the general case and
diverges from the established NVMe model.
So I do not thing we should support this.
