The uptodate parameter of btrfs_writepage_endio_finish_ordered is used to signal whether an error has occured while writing the given page. 0 signal an error, which is propagated to callees and 1 signifies success. In end_compressed_bio_write the ->bi_status is checked and based on it either BLK_STS_OK (0) or BLK_STS_NOTSUPP (1) are used. While from functional point of view this is ok it's a for the poor reader of the code, since the block layer values are conflated with the semantics of the parameter. Just use plain 0 or 1. No functional changes.
