OK, will do tomorrow (sorry, can't do today). > Ooh, the patch triggers RCU warning from task_css().

I didn't expect you will actually apply this patch, I didn't even try to compile it ;) Plus this patch forgets to unconditionalize another threadgroup_change_end() in the error path of copy_process(). Again, if we do this, we can make other cleanups/simplifications. For example, we can kill cgrp_ss_priv[CGROUP_CANFORK_COUNT] in copy_process(). But I see another email from you, will reply in a minute.
