Hello all, We would like to keep this patch for debugging purpose and we will submit another patch which will be compliant with IB-stack sysfs infrastructure once this set of patch are into the mainstream. If any ABI for debugfs is changed, we will follow the changes.

This really is what netlink is for. Remember, debugfs is not a stable ABI area, it could change at any moment, You must not ship tools to end users that process these stats if they come out through debugfs - it is not a way to bypass the kernel API rules. It is just something for developers to use.
