I mispoke before though - it's not the hierarchy's root dentry,

root dentry for the new superblock.  We do know that there must be
a css_set with a cgroup.  I'm still trying to track down whether
that cgrou's inode's dentry can ever be flushed.  I would think
not but am not sure.

Hmmm... I'm not really following.  The inode can be flushed and that's
why it needs to be walked down from root.  What am I missing here?

Thanks.
