Besides the separate pull request that brought Zstd compression support for Btrfs with the in-development Linux 4.14 kernel, the main Btrfs pull request was also submitted on Friday for updating this Linux file-system.

Besides the Zstd compression support, there isn't a whole lot more of end-user exciting work for Btrfs in Linux 4.14. But there is lots of prep work for future features as well as fixes.

Among the changes for Btrfs in Linux 4.14 are deprecating the user transaction ioctl, prep work for better extent reference tracking, prep work for compression heuristics, memory allocation reductions that may also help latencies on busy systems, error handling improvements, more sanity checks, and various other fixes and code clean-ups.

More details on the Btrfs updates for Linux 4.14 via this pull request. I will have some fresh Linux file-system benchmarks of 4.14 (especially with Zstd testing) particularly after the merge window is over.
