Subject: [PATCH v5 02/12] KVM: hide KVM_MEMSLOT_INVALID from userspace
Date: Tue, 07 Aug 2012 17:48:49 +0800	[thread overview]
Message-ID: <5020E481.1050203@linux.vnet.ibm.com> (raw)
In-Reply-To: <5020E423.9080004@linux.vnet.ibm.com>

Quote Avi's comment:
| KVM_MEMSLOT_INVALID is actually an internal symbol, not used by
| userspace.  Please move it to kvm_host.h.

Also, move KVM_MEMSLOT_INVALID to the highest bit
