in this v9 patch, To read max and current value, entry point is common
function rdmacg_resource_read().
This is due to the fact that reading max and current needs to do same
thing. Exceptions are taken care
in below helper functions.
It uses two small helper functions
1. get_cg_rpool_values
2. print_rpool_values
Can I continue with this approach?

o.k.

Also can you please confirm that once patch looks good to you,
you are ok to merge this patch from Doug's linux-rdma tree as merge is
clean from that tree?
