From 80d326fab534a5380e8f6e509a0b9076655a9670 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 24 Feb 2012 14:30:15 +0000 Subject: netlink: add netlink_dump_control structure for netlink_dump_start() Davem considers that the argument list of this interface is getting out of control. This patch tries to address this issue following his proposal: struct netlink_dump_control c = { .dump = dump, .done = done, ... }; netlink_dump_start(..., &c); Suggested by David S. Miller.
