This spews 10000 sparse warnings. I think it may be because of 
the struct_group() magic. Try moving the macros outside of the struct
definition. And make it a static inline while at it, dunno why you used
a define in the first place :S

Please don't repost before Monday just for that, maybe someone will find
time to review over the weekend...
