  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.
