Subject: [mm PATCH v2 01/26] swiotlb: Drop unused functions swiotlb_map_sg and swiotlb_unmap_sg
Date: Wed, 02 Nov 2016 07:12:31 -0400 [thread overview]
Message-ID: <20161102111211.79519.39931.stgit@ahduyck-blue-test.jf.intel.com> (raw)
In-Reply-To: <20161102111031.79519.14741.stgit@ahduyck-blue-test.jf.intel.com>
There are no users for swiotlb_map_sg or swiotlb_unmap_sg so we might as
well just drop them.
Cc: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
