Commit "filemap: update ki_pos in generic_perform_write", made updating of ki_pos into common code in generic_perform_write() function. This also causes generic/091 to fail. This happened due to an in-flight collision with: fb5de4358e1a ("ext2: Move direct-io to use iomap"). I have chosen fixes tag based on which commit got landed later to upstream kernel.
