- Add new optional (off-by-default) parameter "zfsacl:block_special", which automatically adds/removes an empty special ace to prevent ZFS from appending non-inheriting special ACEs during ACL inheritance.
- Make changes to preferentially use fd-based ACL syscalls. Previously zfsacl was only using acl() rather than facl().
- Alter circumstances in which DELETE_CHILD is granted alongside WRITE_DATA (only do this when dealing with special aces).
