From 62322d2554d2f9680c8ace7bbf1f97d8fa84ad1a Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 3 Jul 2006 00:24:21 -0700 Subject: [PATCH] make more file_operation structs static Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..
