From 1ae5dc342ac78d7a42965fd1f323815f6f5ef2c1 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 10 May 2010 05:01:31 -0700 Subject: net: trans_start cleanups Now that core network takes care of trans_start updates, dont do it in drivers themselves, if possible. Drivers can avoid one cache miss (on dev->trans_start) in their start_xmit() handler. Exceptions are NETIF_F_LLTX drivers Signed-off-by: Eric Dumazet Signed-off-by: David S.

It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.
