[v2,0/6] exec: s/group_exit_task/group_exec_task/ for clarity

There is a variable tsk->signal->group_exit_task that is only truly used
in de_thread.  These changes modify the coredump code and the
signal_group_exit() function to stop using group_exit_task, and rename
the group_exit_task variable to group_exec_task.

In addition as I think Linus was asking an additional signal flag is
added called SIGNAL_GROUP_DETHREAD, and that flag is used in the
function signal_group_exit() so that only signal->flags needs to be
tested.

Eric W. Biederman (6):
      signal: Pretty up the SIGNAL_GROUP_FLAGS
      exec: Lock more defensively in exec
      signal: Implement SIGNAL_GROUP_DETHREAD
      signal: In signal_group_exit remove the group_exit_task test
      coredump: Stop using group_exit_task
      exec: Rename group_exit_task group_exec_task and correct the Documentation
