5a279fc5fc In g_zero_destroy_geom(), return 0 instead of EBUSY in the success case.
EBUSY was probably used as a workaround for the deadlock fixed in r207671.

565bc10111 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.
