  "message": "debug: add end-of-oops marker\n\nRight now it\u0027s nearly impossible for parsers that collect kernel crashes\nfrom logs or emails (such as www.kerneloops.org) to detect the\nend-of-oops condition. In addition, it\u0027s not currently possible to\ndetect whether or not 2 oopses that look alike are actually the same\noops reported twice, or are truly two unique oopses.\n\nThis patch adds an end-of-oops marker, and makes the end marker include\na very simple 64-bit random ID to be able to detect duplicate reports.\n\nNormally, this ID is calculated as a late_initcall() (in the hope that\nat that time there is enough entropy to get a unique enough ID); however\nfor early oopses the oops_exit() function needs to generate the ID on\nthe fly.\n\nWe do this all at the _end_ of an oops printout, so this does not impact\nour ability to get the most important portions of a crash out to the\nconsole first.\n\n[ Sidenote: the already existing oopses-since-bootup counter we print\n  during crashes serves as the differentiator between multiple oopses\n  that trigger during the same bootup. ]\n\nTested on 32-bit and 64-bit x86. Artificially injected very early\ncrashes as well, as expected they result in this constant ID after\nmultiple bootups:\n\n  ---[ end trace ca143223eefdc828 ]---\n  ---[ end trace ca143223eefdc828 ]---\n\nbecause the random pools are still all zero. But it all still works\nfine and causes no additional problems (which is the main goal of\ninstrumentation code).\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
