Changes since v1: - fix a missing return - add a new patch to fix a pre-existing missing unmap - various additional cleanups Diffstat: direct.c | 234 +++++++++++++++++++++++++++++++++++++-------------------------- 1 file changed, 138 insertions(+), 96 deletions(-) _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
