ocfs2_dio_wr_get_block always returns -EIO in case of errors. However, some programs expect right exit codes while doing dio. For example, tools like fio treat -ENOSPC as expected code while doing stress jobs. And quota tools expect -EDQUOT when disk quota exceeds. -EIO is too strong return code in the dio path. The caller of ocfs2_dio_wr_get_block is __blockdev_direct_IO which is widely used and it handles error codes well. I have checked functions called by ocfs2_dio_wr_get_block and their return codes look good and clear. So I think it's safe to let ocfs2_dio_wr_get_block return real error code.
