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.

- Fixed a potential deadlock in the UDS index by using the kernel supplied

  struct callback instead of our own implementation of synchronous

  callbacks.

- Eliminated obsolete code and fields from UDS.

- Converted the VDO module to use numeric.h from the UDS module instead of

  having its own version.

- Fixed a bug which would cause incorrect encoding of VDO data structures

  on disk.

- Removed or modified logging which prints pointers from the kernel since

  newer kernels obfuscate the pointer values for security reasons.

- Eliminated confusing and spurious error messages when rebuilding a UDS

  index.

- Improved memory allocation by not using the incorrect __GFP_NORETRY flag

  and by using the memalloc_noio_save mechanism.

- Finished conversion of the encoding and decoding of the VDO's on-disk

  structures to be platform independent.

- Converted VDO to use the atomic API from the UDS module instead of its

  own.

- Fixed memory leaks in UDS error paths.

* Thu Jun 28 2018 - Andy Walsh <awalsh@redhat.com> - 6.2.0.132-4

Note: This is a pre-release version, future versions of VDO may not support

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.

- Adopted use of gcc's built-in byte order macros.

- 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.
