mm: trace-vmscan-postprocess.pl: report the number of file/anon pages respectively
Until now, the reporting from trace-vmscan-postprocess.pl is not very
useful because we cannot directly use this script for checking the
file/anon ratio of scanning. This patch aims to report respectively the
number of file/anon pages which were scanned/reclaimed by kswapd or
direct-reclaim. Sample output is usually something like the following.
Summary
Direct reclaims: 8823
Direct reclaim pages scanned: 2438797
Direct reclaim file pages scanned: 1315200
Direct reclaim anon pages scanned: 1123597
Direct reclaim pages reclaimed: 446139
Direct reclaim file pages reclaimed: 378668
Direct reclaim anon pages reclaimed: 67471
Direct reclaim write file sync I/O: 0
Direct reclaim write anon sync I/O: 0
Direct reclaim write file async I/O: 0
Direct reclaim write anon async I/O: 4240
Wake kswapd requests: 122310
Time stalled direct reclaim: 13.78 seconds
Kswapd wakeups: 25817
Kswapd pages scanned: 170779115
Kswapd file pages scanned: 162725123
Kswapd anon pages scanned: 8053992
Kswapd pages reclaimed: 129065738
Kswapd file pages reclaimed: 128500930
Kswapd anon pages reclaimed: 564808
Kswapd reclaim write file sync I/O: 0
Kswapd reclaim write anon sync I/O: 0
Kswapd reclaim write file async I/O: 36
Kswapd reclaim write anon async I/O: 730730
Time kswapd awake: 1015.50 seconds
