Subject: why the count nr_file_pages is not equal to nr_inactive_file + nr_active_file ?
Date: Fri, 13 May 2016 11:58:16 +0800 [thread overview]
Message-ID: <573550D8.9030507@huawei.com> (raw)
I find the count nr_file_pages is not equal to nr_inactive_file + nr_active_file.
There are 8 cpus, 2 zones in my system.
I think may be the pagevec trigger the problem, but PAGEVEC_SIZE is only 14.
Does anyone know the reason?
Thanks,
Xishi Qiu
