Signed-off-by: Max Reitz <mre...@redhat.com> --- v2: - Use test number which (I hope) no currently pending patch is trying to use [Kevin] - Write 42 bytes instead of 64 so it looks less like a mistake - Mark the test as quick (because it is)
git-backport-diff output against v1: Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively 001/1:[0004] [FC] 'iotests: Add test for dataplane mirroring' Not applied to my block branch because (1) maybe we still want to find out why virtio-blk doesn't assign the BB to its particular AioContext, and (2) because it still doesn't even work without Stefan's ioeventfd series. --- tests/qemu-iotests/127 | 97 ++++++++++++++++++++++++++++++++++++++++++++++ tests/qemu-iotests/127.out | 14 +++++++ tests/qemu-iotests/group | 1 + 3 files changed, 112 insertions(+) create mode 100755 tests/qemu-iotests/127 create mode 100644 tests/qemu-iotests/127.out diff --git a/tests/qemu-iotests/127 b/tests/qemu-iotests/127 new file mode 100755 index 0000000..9e0d7d3 --- /dev/null +++ b/tests/qemu-iotests/127 @@ -0,0 +1,97 @@ +#!/bin/bash +# +# Test case for mirroring with dataplane +# +# Copyright (C) 2017 Red Hat, Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
