Patch title: vmscan-unevictable-lru-scan-sysctl-add-sys_device-parameter.patch
Against: mmotm Jul 14
Applies after: vmscan-unevictable-lru-scan-sysctl-nommu-fix.patch


The second attribute parameter is missing in
read_scan_unevictable_node()/write_scan_unevictable_node().
which has been added recently.
