Subject: Re: unused swap offset / bad page map.
Date: Wed, 7 Aug 2013 11:54:16 -0400 [thread overview]
Message-ID: <20130807155416.GB25515@redhat.com> (raw)

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 ?
Dave
