I am tried to compile and install (network file system)nfs module to kernel i.e. modified nfs code(inserted printk's in kernel nfs code) without compiling entire kernel .
It is inserted but when configuring nfs the mount command crashes. i.e. mount -t nfs 172.16.10.44:/tmp /home/user/ddd

can anyone know why it happens?

Is there any way to do this

Thanks in advance
