i mean for reading swap fault try_to_free_swap in do_swap_page
could hurt clean swap cache pages and make them dirty. it affects
reclaim procedure in shrink_page_list and let this function write
out much more these dirty anonymous pages. in fact these dirty
anonymous pages might keep clean

the purpose of this patch is that when a reading swap fault
happens on a clean swap cache page whose swap count is equal
to one, then try_to_free_swap could remove this page from
swap cache and mark this page dirty. so if later we reclaimed
this page
