From: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx> Subject: proc, meminfo: use correct helpers for calculating LRU sizes in meminfo meminfo_proc_show() and si_mem_available() are using the wrong helpers for calculating the size of the LRUs. The user-visible impact is that there appears to be an abnormally high number of unevictable pages.
