From: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx>
Subject: vmscan: fix sane_reclaim helper for legacy memcg
The sane_reclaim() helper is supposed to return false for memcg reclaim if
the legacy hierarchy is used, because the latter lacks dirty throttling
mechanism, and so it did before it was accidentally broken by commit
33398cf2f360c ("memcg: export struct mem_cgroup"). Fix it.
Fixes: 33398cf2f360c ("memcg: export struct mem_cgroup")
