From 1c677b3d2828a84e0360e1a07d1204531540dc03 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Sat, 3 Dec 2016 16:44:59 +0100 Subject: [PATCH] ipv4: fib: Add fib_info_hold() helper As explained in the previous commit, modules are going to need to take a reference on fib info and then drop it using fib_info_put(). Add the fib_info_hold() helper to make the code more readable and also symmetric with fib_info_put().
