rcu/tasks-trace: Handle new PF_IDLE semantics (2023-11-01 22:12:03 +0100)
----------------------------------------------------------------
RCU fixes for v6.7
* Fix a lock inversion between scheduler and RCU introduced
in v6.2-rc4. The scenario could trigger on any user of RCU_NOCB
(mostly Android and also nohz_full).
* Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking some
RCU-Tasks and RCU-Tasks-Trace expectations as to what exactly is
an idle task. This resulted in potential spurious stalls and
warnings.
