ZFS On Linux Adds New Kernel Support, Asynchronous I/O

A new release of ZFS On Linux is available this week for providing the latest capabilities for this Oracle/Sun ZFS file-system implemented as an out-of-tree, native Linux kernel driver.

The new ZFS On Linux 0.6.4 release is now compatible with kernels up through Linux 4.0. ZFS On Linux 0.6.4 also adds new feature flags of spacemap_histogram, extensible_dataset, bookmarks, enabled_txg, hole)birth, and embedded_data.

Exciting features for ZOL 0.6.4 include asynchronous I/O (AIO) support, LZ4 compression of meta-data, fallocate() punch hole support, new bash completion support, and much more. ZOL's zpool command also has support for some new sub-commands/arguments.

More details on ZFS On Linux 0.6.4 can be found via the release announcement posted to the GitHub project page. I do have plans to do some new, multi-disk ZFS Linux file-system benchmarking, albeit I always seem to run short on time...
