This still has a regression. Commit 1ed70de (from Paul's git tree),
gets a result of 52231880. If I back up two commits to v3.16-rc1 and
revert ac1bea85 (the original culprit) the result goes back up to 57308512.
So something is still going on here.

Running "perf bench numa mem -0 -m -P 1000 -p 8 -t 20" on a 4
node system results in 160 runnable threads on a system with 80
CPU threads.
Once a process has nearly converged, with 39 threads on one node
and 1 thread on another node, the remaining thread will be unable

It seems like RCU is growing in complexity all the time.
Can it be put on a diet in general?
No more new CONFIGs please either.

Reading through the scan period code and comment, it appears the
intent was to slow down NUMA scanning when a majority of accesses
are on the local node, specifically a local:remote ratio of 3:1.
However, the code actually tests local / (local + remote), and

When a task is part of a numa_group, the comparison should always use
the group weight, in order to make workloads converge.

Fix up the best node setting in task_numa_migrate to deal with a task
in a pseudo-interleaved NUMA group, which is already running in the
best location.
Set the task's preferred nid to the current nid, so task migration is
not retried at a high rate.

When CONFIG_FAIR_GROUP_SCHED is enabled, the load that a task places
on a CPU is determined by the group the task is in. This is conveniently
calculated for us by effective_load(), which task_numa_compare should
use.
The active groups on the source and destination CPU can be

The SDM explicitely discourages it.
The 'cycle' event is now handled explicitely, but for others
Running things like the below pointed out a number of situations in
which the current NUMA code has extremely slow task convergence, and
even some situations in which tasks do not converge at all.

Currently the NUMA code scales the load on each node with the
amount of CPU power available on that node, but it does not
apply any adjustment to the load of the task that is being
moved over.
On systems with SMT/HT, this results in a task being weighed
much more heavily than

In case this task is part of a group that is interleaved over
multiple nodes, task_numa_migrate will set the task's preferred
nid to the best node it could find for the task, so

With the introduction of fair queued rwlock, recursive read_lock()
may hang the offending process if there is a write_lock() somewhere
