From 92e1d5be91a0e3ffa5c4697eeb09b2aa22792122 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 12 Feb 2007 00:55:39 -0800 Subject: [PATCH] mark struct inode_operations const 2 Many struct inode_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.
