From 00977a59b951207d38380c75f03a36829950265c Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 12 Feb 2007 00:55:34 -0800 Subject: [PATCH] mark struct file_operations const 6 Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.
