show_task: real_parent

fcfd50af · Roland McGrath <[email protected]> · 2008-01-09 00:03:23 -08:00

The show_task function invoked by sysrq-t et al displays the
pid and parent's pid of each task.  It seems more useful to
show the actual process hierarchy here than who is using
ptrace on each process.
