Subject: Re: [PATCH 10/30] cr: core stuff
Date: Mon, 13 Apr 2009 16:47:01 -0500	[thread overview]
Message-ID: <20090413214701.GA24509@us.ibm.com> (raw)
In-Reply-To: <20090410023539.GK27788@x200.localdomain>

Quoting Alexey Dobriyan (adobriyan@gmail.com):

Hi Alexey,

as far as I can see, the main differences between this patch and the
equivalent in Oren's tree are:

1. kernel auto-selects container init to freeze
2. kernel freezes tasks
3. no objhash taking references
4. no hbuf
5. always require CAP_SYS_ADMIN

Are there other differences which you would consider meaningful?  Which
do you consider the most important?

Also, since Dave introduced the fops->checkpoint(), we (or at least I)
have been struck by the ugly assymetry with checkpoint() being in fops,
and restart() not.  Do you have an idea for fixing that?

thanks,
-serge
