From: Gao Xiang <hsiangkao@xxxxxxxxxxxxxxxxx> commit 1a39ae415c1be1e46f5b3f97d438c7c4adc22b63 upstream. COW extents are already converted into written real extents after xfs_reflink_convert_cow_locked(), therefore cmap->br_state should reflect it. Otherwise, there is another necessary unwritten convertion triggered in xfs_dio_write_end_io() for direct I/O cases. Signed-off-by: Gao Xiang <hsiangkao@xxxxxxxxxxxxxxxxx> Reviewed-by: Darrick J.
