    Subject[PATCH 2/13] md/multipath: Improve another size determination in multipath_run()
    From
    Date
    From: Markus Elfring <elfring@users.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.
