So perf_sigtrap() continues to execute\nand triggers WARN_ON_ONCE(event->ctx->task != current).\n\nSince both task exit and exec paths can call perf_event_exit_task() which\nsets ctx->task to TASK_TOMBSTONE, fix this by explicitly checking if\nevent->ctx->task equals TASK_TOMBSTONE and dropping the redundant\nPF_EXITING check."
