sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c: If available, record the physical path of a vdev in ZFS meta-data. Do this both when opening the vdev, and when receiving an attribute change notification from GEOM. Make vdev_geom_close() synchronous instead of deferring its work to a GEOM event handler. There is no benefit to deferring the work and this prevents a future open call from referencing a consumer that is scheduled for destruction. The close followed by an immediate open will occur during a vdev reprobe triggered by any type of I/O error. Consolidate vdev_geom_close() and vdev_geom_detach() into vdev_geom_close() and vdev_geom_close_locked(). This also moves the cross linking operations between vdev and GEOM consumer into a single place (linking in vdev_geom_attach() and unlinking in vdev_geom_close_locked()).
