  "message": "hw-breakpoints: Improve in-kernel event creation error granularity\n\nIn fail case, perf_event_create_kernel_counter() returns NULL\ninstead of an error, which doesn\u0027t help us to inform the user\nabout the origin of the problem from the outer most callers.\nOften we can just return -EINVAL, which doesn\u0027t help anyone when\nit\u0027s eventually about a memory allocation failure.\n\nThen, this patch makes perf_event_create_kernel_counter() always\nreturn a detailed error code.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nLKML-Reference: \u003c1259210142-5714-2-git-send-regression-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
