It fscking doesn't. He had clearly said that he calls file->f_op->read(), which has nothing whatsofuckingever to descriptors. Sod off and don't return until you learn to read.
As for the original question - grep fro set_fs and you'll see what to do (basically, set_fs(KERNEL_DS) before the call of ->read() and restore afterwards).
