Subject: [PATCH 2/13] md/multipath: Improve another size determination in
 multipath_run()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 1 Oct 2016 20:52:57 +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.
