Hi,

Inorder to support AIO for raw/O_DIRECT, I need to add "struct kiocb *"
to generic_file_direct_IO() and all direct_IO() ops.

generic_file_direct_IO(int rw, struct file *file, const struct iovec *iov,
        loff_t offset, unsigned long nr_segs)

Instead of adding a new argument, I propose replace 

	"struct file *file" argument with "struct kiocb *iocb"

One can get "filp" from iocb->ki_filp.

Any objections ?

Thanks,
Badari
