But NFS ACL is not compatible with POSIX ACL, the one type of ACL Samba can use on Linux platform. Acl_xattr and acl_tdb modules cannot solve problem, because it's required a filesytem with POSIX ACL support for storing generic ACL attrbutes.

As part of the ZFS-on-Linux code, they should provide header files
that allow the vfs_zfsacl to build on Linux. If they don't, then
the project isn't done yet.
