>  - the very small max readahead size

For things like the readahead size, that's probably something that we
should autotune, based the time it takes to read N sectors.  i.e.,
start N relatively small, such as 128k, and then bump it up based on
how long it takes to do a sequential read of N sectors until it hits a
given tunable, which is specified in milliseconds instead of kilobytes.

Unfortunately, that will break ionice and a number of other things...
