Re: [Lse-tech] NUMA sched -> pooling scheduler (inc HT)

[Andrew Theurer]

Thanks Martin, I'll take a look.  One thing I have noticed on B0 numa_sched:
I added node load to /proc/stat and see a problem.  look at procs_running
compared to the total of node1..4.  They do not agree.  It looks as if the
node load and runqueue lengths may have gotten out of sync.  I could not
find any obvious place this happened.
