Raw-io is basically a solution to a problem. As with most solutions there
are advantages and disadvantages. One of the main advantages I see is that
it is a by now well known solution to one set of problems. Perhaps someone
with a deep understanding of the kernel and the problems should take a
step back and look at the problems instead of the various solutions
proposed.
The database problem is one I find the most interesting. Using raw io
basically means we cannot find an abstracted way of describing what we
require of the system, so we do everything by ourself. Of course, that way
anything can be done.
