Subject: [PATCH 07/11] KVM: PPC: Book3S HV: Improve size determinations in five functions
Date: Fri, 20 Jan 2017 19:25:54 +0100 [thread overview]
Message-ID: <83004740-a092-4460-f211-607c5c711e82@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 16:23:30 +0100
Replace the specification of data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
