i have write a block device driver ramdisk program for compilation its getting the error in following code

llc_transfer(dev, req->sector, req->current_nr_sectors, req->buffer, rq_data_dir(req));

the error is
‘struct request’ has no member named ‘sector’

/home/jideesha/ram/ramdisk.c:97: error: ‘struct request’ has no member named ‘current_nr_sectors’
i am using the kernael version 2.6.32.33 generic
for this what is solution

No idea...this is YOUR code, that you wrote. You've given us one line, and a vague kernel (what distro is the kernel running on??)

Best suggestion: this is code that you wrote...no one knows it better than you. So logically, you are the best person to debug the code.

It is there as per the documentation but it seems that the documentation is old!
Perhaps they have changed the API?
Did you look in the file blkdev.h w.r.t your kernel version?

For kernel 2.6.38.8, I couldn't find any member named `current_nr_sectors` in the
`struct request` declaration, in file blkdev.h.
