But please stop call them "semaphores". PI only makes sense for the kind of semaphores called "mutexes" (which can be just a basic semaphore). 2.6.18-rc1 and 2.6.17-rt7 (and earlier) have PI futexes. You still need a patch to glibc. I downloaded it from http://people.redhat.com/mingo/PI-futex-patches/ I have tested it and it works fine (except for a small problem with pthread_mutex_timedlock(), which shouldn't be a problem for 95% of the applications :-) Esben > Thanks > Mark > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > ^ permalink raw reply [flat|nested] 2+ messages in thread
