  "message": "job control: make task_clear_jobctl_pending() clear TRAPPING automatically\n\nJOBCTL_TRAPPING indicates that ptracer is waiting for tracee to\n(re)transit into TRACED.  task_clear_jobctl_pending() must be called\nwhen either tracee enters TRACED or the transition is cancelled for\nsome reason.  The former is achieved by explicitly calling\ntask_clear_jobctl_pending() in ptrace_stop() and the latter by calling\nit at the end of do_signal_stop().\n\nCalling task_clear_jobctl_trapping() at the end of do_signal_stop()\nlimits the scope TRAPPING can be used and is fragile in that seemingly\nunrelated changes to tracee\u0027s control flow can lead to stuck TRAPPING.\n\nWe already have task_clear_jobctl_pending() calls on those cancelling\nevents to clear JOBCTL_STOP_PENDING.  Cancellations can be handled by\nmaking those call sites use JOBCTL_PENDING_MASK instead and updating\ntask_clear_jobctl_pending() such that task_clear_jobctl_trapping() is\ncalled automatically if no stop/trap is pending.\n\nThis patch makes the above changes and removes the fallback\ntask_clear_jobctl_trapping() call from do_signal_stop().\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\n",
