These are bitmasks now, right? Let's make them unsigned int.

Maybe using for_each_set_bit() is better?
#define for_each_subsys_which(ss_mask, ss, ssid) \
for_each_set_bit(ssid, &(ss_mask), CGROUP_SUBSYS_COUNT) \
if ((ss) = group_subsys[ssid] && false) \
; \

^
please drop the space here
Other than the above minor points, looks good to me.
Thanks for the persistence.
