   4 Description:
   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.
