vdo-6.1.0.149-16

The vdo packages provide Virtual Data Optimizer (VDO), which is a block
virtualization technology that allows you to create compressed and deduplicated
pools of block storage.

This update introduces Virtual Data Optimizer (VDO). This feature enables you to
create block devices that transparently provide data deduplication, compression,
and thin provisioning. Standard file systems and applications can run on these
virtual block devices without modification.

VDO is currently available only on the AMD64 and Intel 64 architectures.

Fixed bug(s):
* Sync mode is safe if underlying storage changes to requiring flushes
