You forgot to state why the admin should control that? Each sysctl essentially presents a failure of the automatic tuning algorithms of the kernel (kernel hackers admitting defeat). So a patch adding new ones at least needs a clear rationale what problem it is trying to fix and why the automatic tuning cannot be fixed instead to address this case without new knobs. -Andi -- ak@...ux.intel.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
