  "message": "oom: suppress show_mem() for many nodes in irq context on page alloc failure\n\nWhen a page allocation failure occurs, show_mem() is called to dump the\nstate of the VM so users may understand what happened to get into that\ncondition.\n\nThis output, however, can be extremely verbose.  In irq context, it may\nresult in significant delays that incur NMI watchdog timeouts when the\nmachine is large (we use CONFIG_NODES_SHIFT \u003e 8 here to define a \"large\"\nmachine since the length of the show_mem() output is proportional to the\nnumber of possible nodes).\n\nThis patch suppresses the show_mem() call in irq context when the kernel\nhas CONFIG_NODES_SHIFT \u003e 8.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
