From 056925ab3145713e5e83cf8e05ae6fb2f4ace41e Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sun, 16 Sep 2007 15:42:43 -0700 Subject: [PATCH] [NET]: Cleanup calling netdev notifiers. The call_netdev_notifiers routine can successfully be used in the net/core_dev.c itself. This will save 6 lines of code and 62 ;) bytes of .text section. 62 is rather small, but I have one more patch saving ~30 bytes from netns code (sent to Eric), so altogether they can save some more noticeable amount.
