From ba71d662f2dc3c88d907faf707415c16b8d170d4 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Fri, 3 Oct 2014 15:49:01 +0200 Subject: [PATCH 4/4] qemu-iotests: add multiwrite test cases Message-id: <1412351341-29609-3-git-send-email-stefanha@redhat.com> Patchwork-id: 61569 O-Subject: [RHEV-7.1 qemu-kvm-rhev PATCH 2/2] qemu-iotests: add multiwrite test cases Bugzilla: 1123908 RH-Acked-by: Max Reitz RH-Acked-by: Fam Zheng RH-Acked-by: Markus Armbruster This test case covers the basic bdrv_aio_multiwrite() scenarios: 1. Single request 2. Sequential requests (AABB) 3. Superset overlapping requests (AABBAA) 4. Subset overlapping requests (BBAABB) 5. Head overlapping requests (AABB) 6. Tail overlapping requests (BBAA) 7. Disjoint requests (AA BB) Signed-off-by: Stefan Hajnoczi Reviewed-by: Eric Blake Reviewed-by: Benoit Canet (cherry picked from commit 12ade7609004bb1b09a845c144b36ea1850854c7) Signed-off-by: Stefan Hajnoczi Signed-off-by: Miroslav Rezanina Conflicts: tests/qemu-iotests/group Context conflict due to 099 missing downstream.
