  "message": "ring-buffer: add reader lock\n\nImpact: serialize reader accesses to individual CPU ring buffers\n\nThe code in the ring buffer expects only one reader at a time, but currently\nit puts that requirement on the caller. This is not strong enough, and this\npatch adds a \"reader_lock\" that serializes the access to the reader API\nof the ring buffer.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
