Will both these pages ( the page that holds the buffer_head structure and buffer page that contains the actual data) mapped to the process OR only the page with the buffer_head is mapped to the process ? In other words, the rss value of the process accounts for both these pages or it accounts for only the page with the buffer_head ?
