hm, very interesting. 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.
Ingo
