Subject: Re: [RFC v8][PATCH 11/12] External checkpoint of a task other than ourself
Date: Fri, 31 Oct 2008 08:58:52 -0500	[thread overview]
Message-ID: <20081031135852.GA11641@us.ibm.com> (raw)
In-Reply-To: <1225374675-22850-12-git-send-email-orenl@cs.columbia.edu>

Quoting Oren Laadan (orenl@cs.columbia.edu):
> Now we can do "external" checkpoint, i.e. act on another task.
> 
> sys_checkpoint() now looks up the target pid (in our namespace) and
> checkpoints that corresponding task. That task should be the root of

> 
> sys_restart() remains the same, as the restart is always done in the
> context of the restarting task.

(Have looked this up and down, and it looks good, so while it's the
easiest piece of code to blame for the BUG() I'm getting, it doesn't
seem possible that it is)

Acked-by: Serge Hallyn <serue@us.ibm.com>

thanks, Oren.
