From 647c75ac59a48a54dafd4475d14a645a0025a4f4 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 15 Jun 2017 14:20:39 +0300 Subject: RDMA/netlink: Convert LS to doit callback RDMA_NL_LS protocol is actually does not dump anything, but sets data and it should be handled by doit callback. This patch actually converts RDMA_NL_LS to doit callback, while preserving IWCM and RDMA_CM flows through netlink_dump_start().
