If they use writepage(), then the job of balancing cache cleaning is
done, we just use
writepage as their pressuring mechanism. Any FS that wants to optimize
cleaning
can implement a VFS method, and any FS that wants to optimize freeing
can implement a VFS method,
and all others can use their generic VM current mechanisms.
