Subject: Re: [RFC 2/2] KVM: add virtio-pmem driver
Date: Tue, 17 Oct 2017 00:16:33 -0700	[thread overview]
Message-ID: <20171017071633.GA9207@infradead.org> (raw)
In-Reply-To: <20171012155027.3277-3-pagupta-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

I think this driver is at entirely the wrong level.

If you want to expose pmem to a guest with flushing assist do it
as pmem, and not a block driver.
