[PATCH AUTOSEL for 3.18 49/53] RDMA/cma: Use correct size when writing netlink stats

From: Sasha Levin
Date: Thu Mar 08 2018 - 00:13:54 EST


From: Parav Pandit <parav@xxxxxxxxxxxx>

[ Upstream commit 7baaa49af3716fb31877c61f59b74d029ce15b75 ]

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")
