try_to_free_pages returns the number of pages reclaimed, and the type of
returns is 'unsigned long'. So we should use a matched type for storing
it.
__perform_reclaim() returns an int, so this change is fairly pointless.
However __perform_reclaim()'s single caller expects it to return
unsigned long, so including that change in this patch would make more
sense.
Yeah, thanks for reminding. I will add that and send a v2. :)
