Subject[PATCH 2.6.21-rc4-mm1 0/4] Futexes functionalities and improvements
Hi Andrew,

This is a re-send of a series of patches concerning futexes (here
after is a short description).
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,
