Hi,
I have a small question regarding 'per_cpu_pages' . What is
significance if maintaining 'hot' pages and 'cold' pages list. Are hot
pages something to do with L2 cache (on x86) ?

After going through code, I found out, any new page allocation (for file
read)is from cold page list and zero order pages are generally freed to
hot page list
