Since this is an important futex usecase i started testing it in tip/core/futexes: cd33272: futex: cleanup fshared a135356: futex: use fast_gup() 39ce77b: futex: reduce mmap_sem usage 0d7a336: futex: rely on get_user_pages() for shared futexes Nick, it would be nice to get an Acked-by/Reviewed-by from you, before we think about whether it should go upstream.
