Something looks strange with what kni was doing. Looking at get_user_pages_remote implementation, I see it internally passes FOLL_TOUCH in addition to passed gup_flags. And looking at FOLL_TOUCH definition, it seems natural (to me) that this flag would be handled internally. Maybe it changed over time... but then the question is when did passing FOLL_TOUCH become unneeded? Thanks. -- David Marchand
