Absolutely NOT.

If the swapout code unshares or shares the PMD, that's a major bug.

The swapout code doesn't need to know one way or the other, because the
swapout code never actually touches the pmd itself, it just follows the
pointers - it doesn't ever need to worry about the pmd counts at all.
