Dirty ratio cannot be set to less than 5%. See mm/page-writeback.c:get_dirty_limits(). > or something. Which we already discussed in another thread and almost > already decided we should lower the values for big-mem machines.. We also have an issue with cpusets. Dirty page throttling does not work in a cpuset if it is relatively small to the total memory on the system since we calculate the percentage of the total memory and not a percentage of the memory the process is allowed to use. - 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/
