[Drbd-dev] [PATCH 13/13] DRBD-receiver: Improve determination of sizes in receive_Barrier()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 10 Sep 2016 22:06:21 +0200

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.
