  "message": "ANDROID: mm: Make dump_tasks() safe in NMI context\n\ndump_tasks() can be called from NMI context to dump memory status of all\ntasks. However, calling from NMI context has safety issues:\n1. find_lock_task_mm() acquires task_lock(t) using spin_lock(), which\n   is not NMI-safe and can deadlock if alloc_lock is held when NMI fires.\n2. mem_cgroup_scan_tasks() traverses memcg structures and takes locks\n   that are not NMI-safe.\n\nFix these by:\n- Using spin_trylock(\u0026t-\u003ealloc_lock) in find_lock_task_mm() when in_nmi().\n- Returning early if a memcg oom dump is requested in NMI context.\n\nFixes: 4df28ddcd988 (\"ANDROID: mm: export dump_tasks symbol.\")\nBug: 538262381\nChange-Id: I8b79213015fde74b81427d44f122296c5e0edaf9\nSigned-off-by: Mayank Rungta \u003cmrungta@google.com\u003e\n",
