Lukas Czerner 5a7203947a mm: teach truncate_inode_pages_range() to handle non page aligned ranges ... This commit changes truncate_inode_pages_range() so it can handle non page aligned regions of the truncate. Currently we can hit BUG_ON when the end of the range is not page aligned, but we can handle unaligned start of the range. Being able to handle non page aligned regions of the page can help file system punch_hole implementations and save some work, because once we're holding the page we might as well deal with it right away. In previous commits we've changed ->invalidatepage() prototype to accept 'length' argument to be able to specify range to invalidate. No we can use that new ability in truncate_inode_pages_range().
