page_launder() questions...

[Zlatko Calusic <zlatko@iskon.hr>]

In page_launder():

		/* First time through? Move it to the back of the list */
		if (!launder_loop) {
			list_del(page_lru);
			list_add(page_lru, &inactive_dirty_list);
			UnlockPage(page);
			continue;
		}

Well, it has just found a dirty page and instead of writing it out it
skips it and continues scanning. I don't get it!

Also, all comments speak about swap cache pages, but if I understand
correctly, now even "normal" page cache pages get the dirty bit when
dirtied, so they should also be written out in the page_launder()
function, right?
