BTW, what's for rcnt etc.? I don't see the point. 

They're not (effectively) used in kernel.
I'd suggest to remove these things and to maintain the original ABI.

If rcnt etc. are for other purposes, such as statistics for userspace,
please allocate another structure / interface for it.

(And... cheking size is too strict;
we need to relax it to accept old binaries if we add something
at the tail of structure.)
