Subject: [PATCH V3 1/3] kvm: use kmalloc() instead of kzalloc() during iodev register/unregister
Date: Tue, 25 Aug 2015 17:05:46 +0800	[thread overview]
Message-ID: <1440493548-2971-1-git-send-email-jasowang@redhat.com> (raw)

All fields of kvm_io_range were initialized or copied explicitly
afterwards. So switch to use kmalloc().
