Virtual Data Optimizer (VDO) is a device mapper target that delivers
block-level deduplication, compression, and thin provisioning.
This package provides the kernel modules for VDO.

and by using the memalloc_noio_save mechanism.

structures to be platform independent.

own.

VDO devices created with this version.
- Removed obsolete code.
- Continued conversion of the encoding and decoding of the VDO's on-disk
structures to be platform independent.

- Converted the VDO module to use the platform independent version of the
Murmur3 hash from the UDS module.
- Improved counting of dedupe timeouts by including in the count queries
which are not made due to their being a lack of resources from previous
queries taking too long.
- Improved checking that VDO does not allocate memory from its own threads
during normal operation.
- Fixed a bug which caused crashes with VDO on top of RAID-50.
- Fixed a bug which caused VDO to ignore most flush requests on kernels
later than 4.10
- Resolves: rhbz#1594062
* Thu Jun 21 2018 - Andy Walsh <awalsh@redhat.com> - 6.2.0.109-4
Note: This is a pre-release version, future versions of VDO may not support
VDO devices created with this version.
- Removed obsolete code.
- Made uses of memory barriers and atomics more portable across platforms.
- Converted the encoding and decoding of many of VDO's on-disk structures
to be platform independent.
- Made the implementation of VDO's in-memory data structures platform
independent.
- Fixed a logging bug which resulted in single log message being split
across multiple log lines on newer kernels.
- Fixed a bug which would cause attempts to grow the physical size of a VDO
device to fail if the device below the VDO was resized while the VDO was
offline.
- Converted to use GCC's built-in macros for determining endianness.
- Converted some non-performance critical atomics to be spinlock protected
in order to avoid dealing with memory barrier portability issues.
- Fixed a bug which could cause data loss when discarding unused portions
of a VDO's logical space.
- Reduced memory usage (slightly) by rearranging structures to pack better
in memory.
- Modified grow physical to fail in the prepare step if the size isn't
changing, avoiding a suspend-and-resume cycle.
- Added support for building with a 4.18 kernel.
