Write Clustering: or Getting the VM and the VFS talking

In today disks, we want to minimise seeks times because they are very costly. We use write clustering to minimise them. Currently Linux is not very good at it. The problems are: a) all the interfaces are page/buffer based, and we need context information to be able to do write clustering, b) is that the VM is the layer that knows what information needs to be written, and the VFS knows how to write that information. We need a way to pass that information from one layer to the other without coupling the two subsystems.
