I have checked >> return codes from collees of ocfs2_dio_wr_get_block to make sure > > s/collees/callers The caller of ocfs2_dio_wr_get_block is __blockdev_direct_IO which Is widely used and it handles error codes well. Here I mean the functions called by ocfs2_dio_wr_get_block and their return codes look good and clear. I will make it clear in next version.
