| Description: | |
| This file provides pre-summed memory information for a | |
| process. The format is identical to /proc/pid/smaps, | |
| except instead of an entry for each VMA in a process, | |
| smaps_rollup has a single entry (tagged "[rollup]") | |
| for which each field is the sum of the corresponding | |
| fields from all the maps in /proc/pid/smaps. | |
| For more details, see the procfs man page. | |
| Typical output looks like this: | |
| 00100000-ff709000 ---p 00000000 00:00 0 [rollup] | |
