37 37 * The flags passed to getvmusage() request how to aggregate rss/swap results.
38 38 * Results can be aggregated by zone, project, task, ruser, and/or euser.
39 39 *
40 40 * If VMUSAGE_ALL_* or VMUSAGE_COL_* are passed from a non-global-zone, the
41 41 * flag is treated as VMUSAGE_*. For example, VMUSAGE_ALL_ZONES would be
42 42 * treated as VMUSAGE_ZONE.
43 43 *
44 44 * If VMUSAGE_SYSTEM is passed from a non-global zone, a result of type
45 45 * VMUSAGE_SYSTEM will be returned, but it will only reflect the usage
46 46 * of the calling zone.
47 47 *
48 48 * VMUSAGE_* requests results for the calling zone.
49 49 * VMUSAGE_ALL_* requests results for all zones.
50 50 * VMUSAGE_COL_* requests results for all zones, but collapses out the zoneid.
51 51 * For example, VMUSAGE_COL_PROJECTS requests results for all
52 52 * projects in all zones, and project N in ANY zone is treated
53 53 * as the same project.
