Side note: all of these are obviously still just heuristics. If you really *do* run on a 32-bit kernel, and you want to have the pain, I'm sure you can just disable the dirty limits with a one-liner kernel mod. And if it's useful enough, we can certainly expose flags like that.. Not that I expect that much anybody else will ever care, but it's not like it's wrong to expose the silly heuristics the kernel has to users that have very specific loads. That said, I still do hope you aren't actually using HIGHMEM64G. I was really hoping that the people who had enough moolah to buy >4GB of RAM had long since also upgraded to a 64-bit machine ;) Linus - 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/
