Ok I see. We don't have a way to add to the tail of that list though?
del_page_from_lru() + (new) add_page_to_inactive_list_tail().
Is that a worthwhile addition to this (ever growing) project? That would definitely have an impact on the other code if not all done within swap_prefetch.c.. which would also be quite a large open coded something.
Do both of the above in a new function in swap.c.
That'll require the caller to do lru locking.
I'd add an lru_cache_add_tail, use it instead of the current lru_cache_add
that Con's got now, and just implement it in a simple manner, without
pagevecs.
umm, that's what I said ;)
