From: Wanpeng Li <redacted> Since there are five lists in LRU cache, the array nr in get_scan_count should be: nr[0] = anon inactive pages to scan; nr[1] = anon active pages to scan nr[2] = file inactive pages to scan; nr[3] = file active pages to scan Signed-off-by: Wanpeng Li <redacted> Acked-by: KOSAKI Motohiro <redacted> Acked-by: Minchan Kim <minchan@kernel.org> Reviewed-by: Rik van Riel <redacted> --- mm/vmscan.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
