Well it was rather bolted on the side of the kswapd code. But from an API
perspective, being able to tell it how many page to free is a bit more
flexible. Minor point.
However I'm trying to remember why the code exists at all. Why doesn't
swsusp just allocate lots of pages then free them again?
Something like:
LIST_HEAD(list);
int sleep_count = 0;
while (sleep_count < 10) {
page = __alloc_pages(0, GFP_ATOMIC);
if (page) {
list_add(&page->list, &list);
} else {
blk_congestion_wait(WRITE, HZ/20);
sleep_count++;
}
}
<free all the pages on `list'>
