4Description:
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.
