Full sync for drbd initial usually take a long time, especically when network become the bottleneck the syncing. Simply skip the full sync with "--clear-bitmap" may not the perfect solution for all the cases. So this patches can be used to zero out devices locally instead of a full sync,two make consistent block device. This approach can be useful when lack of network bandwidth to sync.
The patches add one new option "--zap-devices" to "new-current-uuid" to zero out devices. Besides the change of drbd, also need to modify drbd-utils for the flag. All patches are compiled/tested against SLES12.
