From fa027c2a0a0d6d1df6b29ee99048502c93da0dd4 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 12 Feb 2007 00:55:33 -0800 Subject: [PATCH] mark struct file_operations const 4 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.
