Subject: [PATCH 9/9] IB/isert: Improve size determinations in three functions
Date: Fri, 07 Apr 2017 21:09:08 +0000 [thread overview]
Message-ID: <a19efeb8-fd7c-274b-bd59-adbc3a473cfb@users.sourceforge.net> (raw)
In-Reply-To: <ce4249f2-c7e7-0282-2cff-3f9c3991efa3@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 7 Apr 2017 22:20:39 +0200
Replace the specification of three data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determinations a bit safer according to the Linux coding style convention.
