Hmm, definition like this
==
enum {
#ifdef CONFIG_CGROUP_MEM_RES_CTLR
	MEM_RES_CTLR,
#endif
#ifdef CONFIG_CGROURP_BIO
	BIO_CTLR,
#endif
	NR_VM_CTRL,
};

	void	*cgroups[NR_VM_CGROUP];
==
Can save another #ifdefs ?

And, blist seems to be just used for force_empty.
Do you really need this ? no alternative ?


Thanks,
