More information :
- Linux kernel version : 2.6.32 (But I would like a method which is portable to other higher versions as well)
- I tried using follow_page, but this function is not exported from the kernel so, can't use it. (Any reason why this function is not exported??)

Subject: Getting struct page pointer from virtual address
I am working on a linux kernel module and I have a virtual address and mm (struct mm_struct) for a process in this module. I can find the virtaul memory area to which this address belongs to by using find_vma.
Is there a function in the linux kernel which I can use in this module (i.e. exported from the kernel) to get struct page pointer for this virtual address.
