- * @iocb:	IO state structure
- * @iov:	vector with data to write
- * @nr_segs:	number of segments in the vector
- * @pos:	position in file where to write
- *
- * This is a wrapper around __generic_file_aio_write() which takes care of
- * syncing the file in case of O_SYNC file. It does not take i_mutex for the
- * write itself but may do so during syncing. It is meant for users like block
- * devices which do not need i_mutex during write. If your filesystem needs to
- * do a write but already holds i_mutex, use __generic_file_aio_write()
- * directly and then sync the file like generic_file_aio_write().
