Date: Wed, 21 Mar 2007 10:54:32 +0100 From: Pierre.Peiffer@...l.net To: akpm@...ux-foundation.org Cc: mingo@...e.hu, drepper@...hat.com, linux-kernel@...r.kernel.org, jean-pierre.dion@...l.net 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.
