This is a note to let you know that I have just added a patch titled swiotlb-xen: call xen_dma_sync_single_for_device when appropriate to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 8f93bbb9f2f68954ef069e0b73d4e8059b8c9418 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Date: Fri, 21 Nov 2014 16:55:12 +0000 Subject: swiotlb-xen: call xen_dma_sync_single_for_device when appropriate commit 9490c6c67e2f41760de8ece4e4f56f75f84ceb9e upstream. 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.
