Subject: [PATCH] use simpler test_task_thread to test current ti flags
Date: Thu, 28 Jan 2010 17:33:11 -0600	[thread overview]
Message-ID: <20100128233311.GA9890@us.ibm.com> (raw)

This ought to be folded into the 
	'fix 31-bit s390 checkpoint/restart wrappers'
patch which I sent earlier today.  Not a bug without it, just
not as nice.

Signed-off-by: Serge E. Hallyn <serue-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>
