Subject: per-zone and reclaim enhancements for memory controller: add
scan_global_lru macro
From: KAMEZAWA Hiroyuki <[EMAIL PROTECTED]>
This is used to detect which scan_control scans global lru or mem_cgroup lru.
And compiled to be static value (1) when memory controller is not configured.
This may make the meaning obvious.
