    Subject[PATCH 13/14] mm: pincer in truncate_inode_pages_range
    truncate_inode_pages_range()'s final loop has a nice pincer property,
    bringing start and end together, squeezing out the last pages. But
    the range handling missed out on that, just sliding up the range,
    perhaps letting pages come in behind it. Add one more test to give
    it the same pincer effect.
