I don't understand why IBM is pushing this dubious change right now,

It isn't a dubious change, on technical grounds.  It is reasonable for a
distributed filesystem to want to be able to shoot down pte's which map
sections of pagecache.  Just as it is reasonable for the filesystem to be
able to shoot down the pagecache itself.

We've exported much lower-level stuff than this, because some in-kernel
module happened to use it.

Probably not always the right choice, though...  I highly suspect we
far to much of our intestines are easily available.

Again, the whole point of the patch is to -reduce- the degree of
intestinal export.
