It violates the rtmutex semantics badly by introducing\na virtual owner, which hacks around the coupling of the user-space\npi_futex and the kernel internal rt_mutex representation.\n\nAt the moment the only safe option is to remove it fully as it contains\nuser-space visible changes to broken kernel code, which we do not want\nto expose in the 2.6.22 release.\n\nThe patch reverts the original patch mostly 1:1, but contains a couple\nof trivial manual cleanups which were necessary due to patches, which\ntouched the same area of code later.\n\nVerified against the glibc tests and my own PI futex tests.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d0aa7a70bf03b9de9e995ab272293be1f7937822", "tree": "194b30b7b8374b946f166996cb99fb95eb3b7819", "parents": [ "c19384b5b296905d4988c7c684ff540a0f9d65be" ], "author": { "name": "Pierre Peiffer", "email": "pierre.peiffer@bull.net", "time": "Wed May 09 02:35:02 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:55 2007 -0700" }, "message": "futex_requeue_pi optimization\n\nThis patch provides the futex_requeue_pi functionality, which allows some\nthreads waiting on a normal futex to be requeued on the wait-queue of a\nPI-futex.\n\nThis provides an optimization, already used for (normal) futexes, to be used\nwith the PI-futexes.\n\nThis optimization is currently used by the glibc in pthread_broadcast, when\nusing \"normal\" mutexes.
