5	5	This file provides pre-summed memory information for a
6		- process. The format is identical to /proc/pid/smaps,
	6	+ process. The format is almost identical to /proc/pid/smaps,
7	7	except instead of an entry for each VMA in a process,
8	8	smaps_rollup has a single entry (tagged "[rollup]")
9	9	for which each field is the sum of the corresponding
10	10	fields from all the maps in /proc/pid/smaps.
11		- For more details, see the procfs man page.
	11	+ Additionally, the fields Pss_Anon, Pss_File and Pss_Shmem
	12	+ are not present in /proc/pid/smaps. These fields represent
	13	+ the sum of the Pss field of each type (anon, file, shmem).
	14	+ For more details, see Documentation/filesystems/proc.rst
	15	+ and the procfs man page.
