Currently the Linux kernel sets readahead for the entire device, as opposed to individual partitions and that's absolutely inconvenient. For instance, I don't want large readahead numbers for my / and /home partitions, however for my /mnt/media partition setting a high readahead value would be very beneficial. Artem
