Add a very simple and small GEOM class - ZERO. It creates very huge provider (41PB) /dev/gzero. On BIO_READ request it zero-fills bio_data and on BIO_WRITE it does nothing. You can also set kern.geom.zero.clear sysctl to 0 to do nothing even for BIO_READ. I'm using it for performance testing where it is very helpful.
