Add a "REFRATIO" property, which is the compression ratio based on data referenced. For snapshots, this is the same as COMPRESSRATIO, but for filesystems/volumes, the COMPRESSRATIO is based on the data "USED" (ie, includes blocks in children, but not blocks shared with the origin). This is needed to figure out how much space a filesystem would use if it were not compressed (ignoring snapshots).

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
