  "message": "ptrace: wait_task_zombie: do not account traced sub-threads\n\nThe bug is ancient.\n\nIf we trace the sub-thread of our natural child and this sub-thread exits,\nwe update parent-\u003esignal-\u003ecxxx fields.  But we should not do this until\nthe whole thread-group exits, otherwise we account this thread (and all\nother live threads) twice.\n\nAdd the task_detached() check.  No need to check thread_group_empty(),\nwait_consider_task()-\u003edelay_group_leader() already did this.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nCc: Vitaly Mayatskikh \u003cvmayatsk@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
