From: Vitaly Zolotusky <vitaly@xxxxxxxxx> If the IOCB_DSYNC flag is set a sync is not being performed by fuse_file_write_iter. Honor IOCB_DSYNC by invoking generic_write_sync when a write has been successful. generic_write_sync appropriatly syncs the data which was written when IOCB_DSYNC flag is set.
