From a447c0932445f92ce6f4c1bd020f62c5097a7842 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 13 Oct 2008 10:46:57 +0100 Subject: vfs: Use const for kernel parser table This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.
