Subject: [PATCH 02/11] KVM: PPC: Book3S HV: Improve a size determination in kvmppc_alloc_hpt()
Date: Fri, 20 Jan 2017 19:20:50 +0100 [thread overview]
Message-ID: <755544bd-b29c-f240-d526-8a8aec6d620a@users.sourceforge.net> (raw)
In-Reply-To: <fc2c36e6-a453-ae09-89bf-98b3d74113a4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 20 Jan 2017 10:00:13 +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.
