Well binary distro kernels are available that allow easy testing. Will try
with what I got here. I have reproduced it with 3.4 so far.
Its always an mput on a freed memory policy. Slub recovery keeps my system
up at least. I just get the errors dumped to dmesg.
Is there any way to get the trinity tool to stop when the kernel writes
errors to dmesg? That way I could see the parameters passed to mbind?
