If it fails to find a merge or insert the current 2.4 elevator will stick a read at the far end of the request queue. That's quite arbitrary, and is the worst possible thing to do with it.
read-latency2 will put the read a tunable distance from the head. Add a few embellishments to avoid permanent writer starvation, and that's basically all it does.
So rather than just keeping on calling it a "hack" could you please describe what is actually wrong with the idea? - 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/
