| 4 | Description: |
| 5 | This file provides pre-summed memory information for a |
| 6 | process. The format is identical to /proc/pid/smaps, |
| 7 | except instead of an entry for each VMA in a process, |
| 8 | smaps_rollup has a single entry (tagged "[rollup]") |
| 9 | for which each field is the sum of the corresponding |
| 10 | fields from all the maps in /proc/pid/smaps. |
| 11 | For more details, see the procfs man page. |
