Subject: mm: pincer in truncate_inode_pages_range
From: Hugh Dickins <hughd@xxxxxxxxxx>
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.
