Обрабатывает ли Linux KSM страничный кэш? Нет!

KSM only merges anonymous (private) pages, never pagecache (file) pages. KSM's merged pages were originally locked into kernel memory, but can now be swapped out just like other user pages (but sharing is broken when they are swapped back in: ksmd must rediscover their identity and merge again).
