Hi, is there any effective and fast way how to find out whether page given by its page frame number is currenly used by (mapped by) kernel? At the time of checking I can rely that such page: - is not buddy allocator page and also not on per CPU lists - is not compound page - is not reserved page Because I can check that from struct page's flags. I was thinking about using rmap code to find all ptes, but I don't know whether it is not too complicated way. Thanks for all hints. Please add me to Cc, because I am not the list member.
