Some of the new features available with the patch are:
- Boot support for ZFS v28 (only RAIDZ3 is not yet supported). - Various fixes for the existing ZFS boot code. - Support for sendfile(2) (by avg@). - Userland<->kernel compatibility with v13-v15 (by mm@). - ACL fixes (by trasz@).
Unfortunately, due to Oracle's acquisition of Sun, the future of open-source ZFS is uncertain.
