Hello Ming,

I never claimed that commit d4acf3650c7c was a full solution to avoid these
soft lockups. I assume these results mean that patch series "[PATCH 0/7]
Device mapper and dm-mpath fixes" was not applied to the kernel used in your
tests? A colleague of you has reported that that patch series is sufficient
to avoid these soft lockups. See also
