try this

struct file *filp;
mm_segment_t old_fs;
filp = filp_open(name,flags,mode);
old_fs= getfs();
set_fs(KERNEL_DS);
filp->f_op->read(filp,buffer,count,&filp->f_pos);



But you should keep one thing in mind that before this code is executed you
have the filesystem on this this particular file exists has been already
mounted otherwise you risk the crashing of kernel.
