Actually, I'm fairly sure we can do it all inside cgroup_post_fork() because inside cgroup_post_fork() we have access to both the old css_set and the new one. Then it's just a matter of reverting and re-applying the charge to the hierarchies. I'll send a patch in a few days, I need to make sure that this method *actually* works. :P -- Aleksa Sarai (cyphar) www.cyphar.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
