He then reposted with a different version (https://lkml.org/lkml/2012/1/6/281). The later one looks better but I still think this is not worth complicate the code just to get rid of this warning. > > Signed-off-by: Li Zefan > --- > mm/memcontrol.c | 10 ++++++---- > 1 files changed, 6 insertions(+), 4 deletions(-) > > diff --git a/mm/memcontrol.c b/mm/memcontrol.c > index 602207b..c8aeab8 100644 > --- a/mm/memcontrol.c > +++ b/mm/memcontrol.c > @@ -776,14 +776,16 @@ static void memcg_check_events(struct mem_cgroup *memcg, struct page *page) > /* threshold event is triggered in finer grain than soft limit */ > if (unlikely(mem_cgroup_event_ratelimit(memcg, > MEM_CGROUP_TARGET_THRESH))) { > - bool do_softlimit, do_numainfo; > - > - do_softlimit = mem_cgroup_event_ratelimit(memcg, > - MEM_CGROUP_TARGET_SOFTLIMIT); > + bool do_softlimit; > #if MAX_NUMNODES > 1 > + bool do_numainfo; > + > do_numainfo = mem_cgroup_event_ratelimit(memcg, > MEM_CGROUP_TARGET_NUMAINFO); > #endif > + > + do_softlimit = mem_cgroup_event_ratelimit(memcg, > + MEM_CGROUP_TARGET_SOFTLIMIT); > preempt_enable(); > > mem_cgroup_threshold(memcg); > -- > 1.7.3.1 > > -- > To unsubscribe, send a message with 'unsubscribe linux-mm' in > the body to majordomo@kvack.org.
