What about a swapfile (on ext4 or XFS) onr a thin volume? In this case, I'd expect fallocate would set the LE to PE mapping, and it should work. But does it work for both paging and hibernation files?
If things did not change, fallocate does *not* allocate PE space (ie: they are not passed down to the underlying thin pool).
Moreover, I expect for a memory-starved machine to page out pool metadata (right?) so I would not use a thin volume for swap.
