    context_tracking: ipipe: do not track over the head domain · 58992a82

    Context tracking is a prerequisite for FULL_NOHZ, so that the RCU
    subsystem can detect CPU idleness without relying on the (regular)
    timer tick.
    
    Out-of-band activity running over the head domain should by definition
    not be involved in such detection logic, as the root domain has no
    knowledge of what happens - and when - on the head domain whatsoever.
