[PATCH] Fix the error handling in direct I/O
Fix a bug on error handling in the direct I/O function. Currently, if a file is opened with the O_DIRECT|O_SYNC flag, the write() syscall cannot receive the EIO error after an I/O error (SCSI cable is disconnected etc.). Return values of other points that call generic_osync_inode() are treated appropriately.
