Description:
This file provides pre-summed memory information for a
- process. The format is identical to /proc/pid/smaps,
+ 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.
- For more details, see the procfs man page.
+ 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.txt
+ and the procfs man page.
