* The flags passed to getvmusage() request how to aggregate rss/swap results.
* Results can be aggregated by zone, project, task, ruser, and/or euser.
*
* If VMUSAGE_ALL_* or VMUSAGE_COL_* are passed from a non-global-zone, the
* flag is treated as VMUSAGE_*. For example, VMUSAGE_ALL_ZONES would be
* treated as VMUSAGE_ZONE.
*
* If VMUSAGE_SYSTEM is passed from a non-global zone, a result of type
* VMUSAGE_SYSTEM will be returned, but it will only reflect the usage
* of the calling zone.
*
* VMUSAGE_* requests results for the calling zone.
* VMUSAGE_ALL_* requests results for all zones.
* VMUSAGE_COL_* requests results for all zones, but collapses out the zoneid.
* For example, VMUSAGE_COL_PROJECTS requests results for all
* projects in all zones, and project N in ANY zone is treated
* as the same project.
