Please don't. Whenever you think you priority inheritance, it's a sign your system has got too complicated. The simplest solution is to simply have no priorities when a task is in-kernel (or at least non that can completely exclude a task). - 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/
