Subject: [PATCH] show_task: real_parent
Date: Wed,  9 Jan 2008 00:03:23 -0800 (PST)	[thread overview]
Message-ID: <20080109080323.8FCDC26F9A7@magilla.localdomain> (raw)


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.
