If you want to start that game, explain where you got the idea that
Linux's filesystems and IO subsystems were _ever_ designed to be able to
make guarantees about IO bandwidth at all!

There's a whole raft of code which would have to be rethought before we
could make any such promises, right from the device drivers and the IO
request layer up to the filesystem[s].
