Message-ID: <1416589220-7720-1-git-send-email-stefano.stabellini@eu.citrix.com> Date: Fri, 21 Nov 2014 17:00:19 +0000 From: Stefano Stabellini <stefano.stabellini@...citrix.com> To: <xen-devel@...ts.xensource.com> CC: <konrad.wilk@...cle.com>, <Stefano.Stabellini@...citrix.com>, <david.vrabel@...rix.com>, <linux-kernel@...r.kernel.org>, Stefano Stabellini <stefano.stabellini@...citrix.com>, <stable@...r.kernel.org> Subject: [PATCH 1/2] swiotlb-xen: call xen_dma_sync_single_for_device when appropriate In xen_swiotlb_sync_single we always call xen_dma_sync_single_for_cpu, even when we should call xen_dma_sync_single_for_device. Fix that.
