[PATCH 09/13] DRBD-receiver: Improve determination of sizes in receive_SyncParam()

From: SF Markus Elfring
Date: Sat Sep 10 2016 - 16:32:30 EST


From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

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.
