Subject: Re: [PATCH 4/5] IB: Switch from struct ib_dma_mapping_ops to struct dma_mapping_ops
Date: Fri, 9 Dec 2016 19:24:29 +0100	[thread overview]
Message-ID: <20161209182429.GF16622@lst.de> (raw)
In-Reply-To: <25d066c2-59d7-2be7-dd56-e29e99b43620-XdAiOPVOjttBDgjK7y7TUQ@public.gmane.org>

> Additionally, use dma_noop_ops instead of duplicating it.

Oops, I don't think that part actually is correct.  Both rdmavt
and the weird intel drivers want the _virtual_ address in their dma
address instead of the physical one set by dma_noop_ops.
