init_mm linked list problem

["Jason J. Herne" <hernejj@xxxxxxxxxxxx>]

Can anyone tell me why the following code would STOP working if I
upgraded from kernel version 2.6.8.1 to 2.6.11.6??  

I just want to be able to visit all of the mm_struct's that exist on the
system.  This code worked just fine (at least it seemed to), and then I
upgraded my kernel version and now mcount prints to the log file with a
value of 0.  Before I was getting 60-70 depending on how many processes
I had running.  

int mcount=0;
struct mm_struct *m;

spin_lock(&mmlist_lock);
list_for_each_entry(m, &init_mm.mmlist, mmlist)
{
	mcount++;

	/* Do stuff */	
}
spin_unlock(&mmlist_lock);

printk("mm_struct count: %d\n", mcount);
