[PATCH 3.16 088/410] RDMA/cma: Use correct size when writing netlink stats

From: Ben Hutchings
Date: Thu Jun 07 2018 - 12:05:51 EST


3.16.57-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Parav Pandit <parav@xxxxxxxxxxxx>

commit 7baaa49af3716fb31877c61f59b74d029ce15b75 upstream.

The code was using the src size when formatting the dst. They are almost
certainly the same value but it reads wrong.

Fixes: ce117ffac2e9 ("RDMA/cma: Export AF_IB statistics")
