I can't give you an absolutely authoritative answer, but because of the way hugepages are implemented and allocated, I
can'tthink how they could be used for other processes.  Linux hugepages are either 2m or 1g, far too large for any
likelyprocesses to require. They cannot be allocated in partial pages.
