36  * The flags passed to getvmusage() request how to aggregate rss/swap results.
37  * Results can be aggregated by zone, project, task, ruser, and/or euser.
38  *
39  * If VMUSAGE_ALL_* or VMUSAGE_COL_* are passed from a non-global-zone, the
40  * flag is treated as VMUSAGE_*.  For example, VMUSAGE_ALL_ZONES would be
41  * treated as VMUSAGE_ZONE.
42  *
43  * If VMUSAGE_SYSTEM is passed from a non-global zone, a result of type
44  * VMUSAGE_SYSTEM will be returned, but it will only reflect the usage
45  * of the calling zone.
46  *
47  * VMUSAGE_*	 requests results for the calling zone.
48  * VMUSAGE_ALL_* requests results for all zones.
49  * VMUSAGE_COL_* requests results for all zones, but collapses out the zoneid.
50  *		 For example, VMUSAGE_COL_PROJECTS requests results for all
51  *		 projects in all zones, and project N in ANY zone is treated
52  *		 as the same project.
