Subject: [PATCH 9/9] KVM: Improve another size determination in kvm_create_vm()
Date: Sun, 22 Jan 2017 18:19:02 +0000 [thread overview]
Message-ID: <3de25179-996a-1fc9-2cdd-80f0e524486a@users.sourceforge.net> (raw)
In-Reply-To: <a2fb541a-7a7d-1f78-b587-1191b9832088@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 22 Jan 2017 18:56:26 +0100
Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
