Subject: [Question]: about the paramters of func generic_file_buffered_write.

Hi all,
	The definition of func generic_file_buffered_write is:
 		ssize_t generic_file_buffered_write(struct kiocb *, const struct iovec *,
                							unsigned long, loff_t, loff_t *, size_t, ssize_t);
The fourth and fifth paratmers indicate the current pos of file.
Every place which call this function, it set the fourth to iocb->ki_pos(maybe not but equal).
The fifth parameter is set &iocb->ki_pos.

I think we can remove two parameters. Those parameter can replace by the files of struct kiocb in the fun
of generic_file_buffered_write.

Or am i missing something?

Thansk!
