Hello Everyone,
These Patches add support for continuous replication to colo. This
means that after the Primary fails and the Secondary did a failover,
the Secondary can then become Primary and resume replication to a new
Secondary.
Regards,
Lukas Straub

Hello Everyone,
So I guess this is ready for merging or will that have to wait until the 4.2
release is done?
Due to Qemu 4.2 release schedule, after soft feature freeze(Oct29) the master
branch does not accept feature changes.
But I don't know if sub-maintainer(block or net) can queue this series first
then merge it after 4.2 release?
Thanks
Zhang Chen
Will try to queue this series.
Thanks
Regards,
Lukas Straub
