        external/cddl/osnet/dist/uts/common/fs/zfs/zvol.c: revision 1.14

zvol: Implement DIOCCACHESYNC

Similarly to FreeBSD, simply call zil_commit when the DIOCCACHESYNC
ioctl is invoked on a zvol.

Tested in a xen dom0 with a domU's xbds provided by zvol on dom0.  The
error message about DIOCCACHESYNC is gone, and (mysteriously)
operations in the domU seem faster.

Thanks to Michael van Elst via port-xen@ for pointing out where/how to
do this.
