Subject: [PATCH 0/3] ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Precedence: bulk


Recently I had a conversation where it was pointed out to me that
SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
difficult for a tracer to handle.

Keeping SIGKILL working for anything after the process has been killed
is also a real pain from an implementation point of view.

So I am attempting to remove this wart in the userspace API and see
if anyone cares.

      signal: Ensure SIGNAL_GROUP_EXIT gets set in do_group_exit
      signal: Guarantee that SIGNAL_GROUP_EXIT is set on process exit
      signal: Drop signals received after a fatal signal has been processed
