Hi Paul,

I have confirmed that there's no such issue on commit 6a87dff9f33a,
but I'm not sure the commit fixed the issue, I can't find the error on
parent commit 24a9c54182b3 too.

  $ git log --oneline -2 6a87dff9f33a
  6a87dff9f33af context_tracking: Take idle eqs entrypoints over RCU
  24a9c54182b37 context_tracking: Split user tracking Kconfig

Best Regards,
Rong Chen
