Be *very* careful doing this - it's a really good way to splat your
system in a hurry.  Unless you're *really* sure that none of the 'struct *'
you use changed size or members, you'll trash something.  And it's quite
possible for the *same* kernel to have different sizes for stuff (for instance,
building a UP or SMP version).

You got lucky here.  A worse possibility is that it *found* the symbol, but
you have a type mysmatch (number of arguments, int/long long/short issues, etc),
which will result in the symbol being found, but things going pear-shaped soon
thereafter.....
