block_invalidatepage(): only release page if the full page was invalidated
Prior to commit d47992f86b30 ("mm: change invalidatepage prototype to accept length"), an offset of 0 meant that the full page was being invalidated. After that commit, we need to instead check the length. Jan said: : : The only possible issue is that try_to_release_page() was called more : often than necessary. Otherwise the issue is harmless but still it's good : to have this fixed.
