+What:		/proc/pid/smaps_rollup
+Date:		August 2017
+Contact:	Daniel Colascione <dancol@google.com>
+Description:
+		This file provides pre-summed memory information for a
+		process.  The format is almost 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.
+		Additionally, the fields Pss_Anon, Pss_File and Pss_Shmem
+		are not present in /proc/pid/smaps.  These fields represent
+		the sum of the Pss field of each type (anon, file, shmem).
+		For more details, see Documentation/filesystems/proc.rst
+		and the procfs man page.
+
+		Typical output looks like this::
