Jim: Great work on tracking down these issues, I am curious are they addressed in the newer 3.10 series from CentOS or only from other upstream sources? If they are from other uptream sources, has it been reported to CentOS/Redhat? More curious than anything else, not a requirement. I do agree that we should make the changes to both kernel. Sau!

Hi Folks,
I have identified 3 kernel patches to fix the observed memory leak in the RT kernel. Namely listed here in comment 53: https://bugs.launchpad.net/starlingx/+bug/1836638/comments/53
While the leak is only really seen in RT, the fixes are not RT specific. The RT kernel has ferreted out many linux bugs in the past mainly due to its different scheduling points, and running irq handlers as kernel threads, causing things to run in a different order from std.
So should these patches be applied to both of our kernels, even though we only see the leaking on RT? I would say yes, but don't want to waste my, and possibly Yi's, time if approvers disagree.
Thanks,
-Jim
