That preceding commit corrected a little mismanagement regarding the MEMINFO_MEM_CACHED enumerator, which was used in the following programs: free, top plus vmstat. This patch simply adapts those programs to use the new MEMINFO_MEM_CACHED_ALL enumerator, which reflects both the 'Cached' plus 'SReclaimable' values they expected.
