Subject: [PATCH 4/7] kernel-trace: Improve a size determination in create_hist_field()
Date: Fri, 5 May 2017 23:04:29 +0200 [thread overview]
Message-ID: <8b0724f4-18aa-c31d-8969-883816efbd2b@users.sourceforge.net> (raw)
In-Reply-To: <3419381c-6a8f-f0f6-86e8-3ee7f9af0076@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 5 May 2017 20:15:46 +0200
Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
