From 88e9d34c727883d7d6f02cf1475b3ec98b8480c7 Mon Sep 17 00:00:00 2001 From: James Morris Date: Tue, 22 Sep 2009 16:43:43 -0700 Subject: seq_file: constify seq_operations Make all seq_operations structs const, to help mitigate against revectoring user-triggerable function pointers. This is derived from the grsecurity patch, although generated from scratch because it's simpler than extracting the changes from there.
