  "message": "rcu: Check for callback invocation from offline CPUs\n\nBecause quiescent states are now reported from offline CPUs in\nCPU_DYING state, there is some possibility that such a CPU might\nnote the end of a grace period and attempt to start invoking\ncallbacks.  This would be a very bad thing, and is supposed to\nbe prevented by the fact that the CPU_DYING CPU gets rid of all\nits callbacks before reporting the quiescent state.  However,\nthere is other CPU-offline code in the kernel, and it is quite\npossible that someone will invoke RCU core processing from that\ncode.  Therefore, this commit adds a warning for this case.\n\nSigned-off-by: Paul E. McKenney \u003cpaul.mckenney@linaro.org\u003e\nSigned-off-by: Paul E.
