+
+* Wed Aug 8 2018 - Andy Walsh <awalsh@redhat.com> - 6.2.0.197-6

+
+* Sat Jul 28 2018 - Andy Walsh <awalsh@redhat.com> - 6.2.0.187-6

+ having its own version.
+- Fixed a bug which would cause incorrect encoding of VDO data structures

+ newer kernels obfuscate the pointer values for security reasons.
+- Eliminated confusing and spurious error messages when rebuilding a UDS
+ index.

+ and by using the memalloc_noio_save mechanism.

+ 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

+ 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.

+
+* Thu Jun 21 2018 - Andy Walsh <awalsh@redhat.com> - 6.2.0.109-4

+- 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.

+ in memory.
+- Modified grow physical to fail in the prepare step if the size isn't
+ changing, avoiding a suspend-and-resume cycle.
