Resolves: rhbz#1609178 - 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. -

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. - 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 - 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. -
