I've read the code, and I've read the comments (well, I've hunted for some) and I've read the docs. I really don't know how anyone could use this in its current state without doing a lot of code-reading and complex experimentation. All of which would be unneeded if this tunable was properly documented. So. Please provide adequate documentation for this tunable. I'd suggest that it be pitched at the level of a reasonably competent system operator. It should help them understand why the tunable exists, why they might choose to alter it, and what effects they can expect to see. Hopefully a reaonably competent kernel developer can then understand it too. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
