No, and I'm not sure I agree with you at first glance. Is this just generally an idea that data stored on SSD should not be in RAM? If so, there's no mechanism for that other than using direct I/O.

It would be similar to using O_DIRECT, but on a per-extent basis. Is there a mechanism for that already?
