From 511e936bf2b3e8be2a3160ace3d86be07962a7a8 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 12 May 2017 15:36:49 +0200 Subject: sunrpc: mark all struct rpc_procinfo instances as const struct rpc_procinfo contains function pointers, and marking it as constant avoids it being able to be used as an attach vector for code injections.
