Cover letter [PATCH 2.6.20-rc4 0/4] futexes functionalities and improvements
Hi,
Today, there are several functionalities or improvements about futexes included in -rt kernel tree, which, I think, it make sense to have in mainline. Among them, there are:
* futex use prio list : allow threads to be woken in priority order instead of
FIFO order.
* futex_wait use hrtimer : allow the use of finer timer resolution.
* futex_requeue_pi functionality : allow use of requeue optimisation for
PI-mutexes/PI-futexes.
* futex64 syscall : allow use of 64-bit futexes instead of 32-bit.
The following mails provide the corresponding patches.
Comments, suggestions, feedback, etc are welcome, as usual.
