Subject: [PATCH 09/13] DRBD-receiver: Improve determination of sizes in receive_SyncParam()
Date: Sat, 10 Sep 2016 22:32:17 +0200 [thread overview]
Message-ID: <334ae3df-8fff-025b-5311-af4522d9611f@users.sourceforge.net> (raw)
In-Reply-To: <3566e764-27b8-82e5-1f8e-c613e5a3a5b1@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 10 Sep 2016 21:54:55 +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.
