mm: add max swappiness arg to lru_gen for anonymous memory only
The MGLRU already supports reclaiming only from anonymous memory via the
/sys/kernel/debug/lru_gen interface. Now, memory.reclaim also supports
the swappiness=max parameter to enable reclaiming solely from anonymous
memory. To unify the semantics of proactive reclaiming from anonymous
folios, the max parameter is introduced.
