void __lru_cache_add(struct page *page)
{
struct pagevec *pvec = &get_cpu_var(lru_add_pvec);
page_cache_get(page);
if (!pagevec_space(pvec))
__pagevec_lru_add(pvec);
pagevec_add(pvec, page);
put_cpu_var(lru_add_pvec);
}
I added a printk, and found that pagevec_add frequently returns 0. Is that ok ?
What happens to 'page' in this case ?
