Hi,
Matti Aarnio:

There cannot be write-ahead (the data either hasn't been written yet, or
it's still too "hot"), but there's the possibility of write-behind.
That is, if you have look at page N, which needs to be written, check
N-1 and N-2 and ... to see if they are dirty too. If so, write them.

Under Linux, that's the same thing... right?
