It depends on what kind of PI under specific circumstances. In the general kernel, it's really to be avoided at all costs since it's masking a general contention problem at those places. In a formally provable worst case system using priority ceiling emulation and stuff, PI really valuable. How a system like the Linux kernel fits into that is a totally different story. General purpose kernels using general purpose facilities don't. That's how I see it. bill - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
