They can be manually disabled via /sys (and\nalso re-enabled via /sys), and are automatically disabled upon panic.\nHowever, some users need RCU CPU stalls to be disabled at boot time,\nbut to be enabled without rebuilding/rebooting. For example, someone\nrunning a real-time application in production might not want the\nadditional latency of RCU CPU stall detection in normal operation, but\nmight need to enable it at any point for fault isolation purposes.\n\nThis commit therefore provides a new CONFIG_RCU_CPU_STALL_DETECTOR_RUNNABLE\nkernel configuration parameter that maintains the current behavior\n(enable at boot) by default, but allows a kernel to be configured\nwith RCU CPU stall detection built into the kernel, but disabled at\nboot time.\n\nRequested-by: Clark Williams \u003cwilliams@redhat.com\u003e\nRequested-by: John Kacur \u003cjkacur@redhat.com\u003e\nSigned-off-by: Paul E.
