I'm not sure what the "Suresh had problems" comment refers to - perhaps a
now-removed patch.
afaik, the load balancing problem which Peter observed remains unresolved.
I have not seen this problem on recent -mm kernels (-rc6-mm1 and
-rc6-mm2 even with SCHED_MC configured in) so it would appear that it's
fixed. The only worrying thing is that we don't know what fixed it.
Has smpnice had appropriate testing for regressions?
There've been no reported problems for quite a while so my (biased)
answer would be "yes".
