[lustre-discuss] Avoiding system cache when using ssd pfl extent

When using PFL, and using an SSD as the first extent, it seems it would 
be advantageous to not have that extent's file data consume memory in 
the client's system buffers.  It would be similar to using O_DIRECT, but 
on a per-extent basis.  Is there a mechanism for that already?
