I will inspect if i could combine it with the "real-time interrupts" i recently described (http://www.linuxdevices.com/articles/AT6105045931.html). Currently i'm protecting critical areas with "prioritized spinlocks" that don't provide a priority inversion aviodance scheme. Having "real" mutexes with priority inheritence should be pretty helpfull to make the kernel hard real time aware. best regards Bernhard - 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/
