Code that does page outs

[Eugene Teo <eugene.teo@eugeneteo.net>]

I am looking for possible areas in the kernel code where
page outs occurs. I have looked at shrink_cache(), and 
swap_out_pmd() which calls try_to_swap_out(). 

Are there other areas that i missed out? 

I am looking at the areas where page outs will occur so that
I can keep track of 

1) number of page outs occurred at an arbitrary time.
2) what causes the page outs.

Anticipating a reply...

Eugene
