Description Fam Zheng 2016-06-22 02:32:16 UTC

The problem was originally reported by "Denis V. Lunev" <den> as "bdrv_co_discard must mark areas dirty after writing zeroes, it must call
before_write_notifier chain to push underlying data to backup and it also
must properly fill tracked request information."

Backport the upstream 2.7 candidate patches to fix it.

Comment 4 Miroslav Rezanina 2016-06-23 08:46:08 UTC

Fix included in qemu-kvm-rhev-2.6.0-9.el7

Comment 7 Fam Zheng 2016-09-13 02:25:22 UTC

Yes, I think so.
