given a vma, how can I walk all the pages?

[Anthony Golia <Anthony.Golia@morganstanley.com>]

Hi.  I'm trying to get the page structs for all the pages in a vma.  in
2.4.18 it looks like mm_follow_page (from memory.c) would do it?  Like,
I could do:

for (vma = t->mm->mmap; vma; vma = vma->vm_next) {
		/* loop thru all the pages in this vma */
		addr = vma->vm_start;
		while (addr < vma->vm_end ) { 
			apage = mm_follow_page(t->mm, addr, 0);
			addr += PAGE_SIZE;
			
		}
}

but the machine hangs when I do this.
any help is appreciated.
