Subject: [PATCH 07/15] md-cluster: Improve another size determination in
 process_suspend_info()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 12:42:50 +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.
