Thank you Andi.

I did grep for "struct file_operations" in mm:

paolo@...lo-desktop:~/linux-2.6/mm$ grep "struct file_operations" *
shmem.c:static const struct file_operations shmem_file_operations;
shmem.c:static const struct file_operations shmem_file_operations = {
swapfile.c:static const struct file_operations proc_swaps_operations = {

Am I right in saying that both the files don't need to be modified?

There is nothing like:
struct file_operations xyz_ops = {
       ...
       .ioctl = xyz_ioctl
};

in there.

So I guess I need a smarter trick to find out which files need to be modified
as you previously suggested.

Ciao,
