  "message": "percpu-refcount: implement percpu_ref_cancel_init()\n\nNormally, percpu_ref_init() initializes and percpu_ref_kill*()\ninitiates destruction which completes asynchronously.  The\nasynchronous destruction can be problematic in init failure path where\nthe caller wants to destroy half-constructed object - distinguishing\nhalf-constructed objects from the usual release method can be painful\nfor complex objects.\n\nThis patch implements percpu_ref_cancel_init() which synchronously\ndestroys the percpu_ref without invoking release.  To avoid\nunintentional misuses, the function requires the ref to have finished\npercpu_ref_init() but never used and triggers WARN otherwise.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
