From 9b5b5cff9a6655dbb6d2e2be365bb95eec3950eb Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Tue, 29 Nov 2005 16:21:38 -0800 Subject: [NET]: Add const markers to various variables. the patch below marks various variables const in net/; the goal is to move them to the .rodata section so that they can't false-share cachelines with things that get written to, as well as potentially helping gcc a bit with optimisations. (these were found using a gcc patch to warn about such variables) Signed-off-by: Arjan van de Ven Signed-off-by: David S.
