  "message": "tracing: add trace event for memory-failure\n\nRAS user space tools like rasdaemon which base on trace event, could\nreceive mce error event, but no memory recovery result event.  So, I want\nto add this event to make this scenario complete.\n\nThis patch add a event at ras group for memory-failure.\n\nThe output like below:\n#  tracer: nop\n#\n#  entries-in-buffer/entries-written: 2/2   #P:24\n#\n#                               _-----\u003d\u003e irqs-off\n#                              / _----\u003d\u003e need-resched\n#                             | / _---\u003d\u003e hardirq/softirq\n#                             || / _--\u003d\u003e preempt-depth\n#                             ||| /     delay\n#            TASK-PID   CPU#  ||||    TIMESTAMP  FUNCTION\n#               | |       |   ||||       |         |\n       mce-inject-13150 [001] ....   277.019359: memory_failure_event: pfn 0x19869: recovery action for free buddy page: Delayed\n\n[xiexiuqi@huawei.com: fix build error]\nSigned-off-by: Xie XiuQi \u003cxiexiuqi@huawei.com\u003e\nReviewed-by: Naoya Horiguchi \u003cn-horiguchi@ah.jp.nec.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Chen Gong \u003cgong.chen@linux.intel.com\u003e\nCc: Jim Davis \u003cjim.epost@gmail.com\u003e\nSigned-off-by: Xie XiuQi \u003cxiexiuqi@huawei.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
