From 11b46a271d73631177f59ff581a408f967c30fb9 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Fri, 9 May 2025 15:40:22 -0500 Subject: [PATCH 05/14] iotests: Improve iotest 194 to mirror data RH-Author: Eric Blake RH-MergeRequest: 363: blockdev-mirror: More efficient handling of sparse mirrors RH-Jira: RHEL-88435 RHEL-88437 RH-Acked-by: Stefan Hajnoczi RH-Acked-by: Miroslav Rezanina RH-Commit: [5/14] 9f1fd3c7d4332ac310af4eb37e8f2122f6324294 (ebblake/centos-qemu-kvm) Mirroring a completely sparse image to a sparse destination should be practically instantaneous. It isn't yet, but the test will be more realistic if it has some non-zero to mirror as well as the holes.
