Wen Congyang 06c3916b35 Backup: don't do copy-on-read in before_write_notifier ... We will copy data in before_write_notifier to do backup. It is a nested I/O request, so we cannot do copy-on-read. The steps to reproduce it: 1. -drive copy-on-read=on,... // qemu option 2. drive_backup -f disk0 /path_to_backup.img // monitor command Signed-off-by: Wen Congyang <wency@cn.fujitsu.com> Tested-by: Jeff Cody <jcody@redhat.com> Message-id: 1441682913-14320-3-git-send-email-wency@cn.fujitsu.com Signed-off-by: Jeff Cody <jcody@redhat.com>		2015-09-25 08:37:07 -04:00
