I have reworked the patches to take into account the last changes about futex, and this series should apply cleanly on -mm tree (the changes mostly affect patch 2 "futex_wait uses hrtimer") I also took into account the remark of Peter Zijlstra in patch 3 concerning futex_requeue_pi. Could you consider (again) them for inclusion in -mm tree ? All of them have already been discussed in January and have already been included in -rt for a while. I think that we agreed to potentially include them in the -mm tree. And, again, Ulrich is specially interested by sys_futex64. There are: * futex uses prio list : allows RT-threads to be woken in priority order instead of FIFO order. * futex_wait uses hrtimer : allows the use of finer timer resolution. * futex_requeue_pi functionality : allows use of requeue optimization for PI-mutexes/PI-futexes. * futex64 syscall : allows use of 64-bit futexes instead of 32-bit. Thanks, -- Pierre P.
