From 3dea7ca7160f80dd6d31c0bbeb2d871e51b567b6 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 1 Aug 2007 10:12:22 +1000 Subject: [PATCH] KVM: Remove stat_set from debugfs We shouldn't define stat_set on the debug attributes, since that will cause silent failure on writing: without a set argument, userspace will get -EACCESS.
