From 44b5ce73c99c389817be71b9161bceb197d40ecb Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Tue, 26 Aug 2014 14:00:38 +0200 Subject: [PATCH] KVM: Unconditionally export KVM_CAP_USER_NMI The idea between capabilities and the KVM_CHECK_EXTENSION ioctl is that userspace can, at run-time, determine if a feature is supported or not. This allows KVM to being supporting a new feature with a new kernel version without any need to update user space. Unfortunately, since the definition of KVM_CAP_USER_NMI was guarded by #ifdef __KVM_HAVE_USER_NMI, such discovery still required a user space update. Therefore, unconditionally export KVM_CAP_USER_NMI and change the the typo in the comment for the IOCTL number definition as well.
