  [PATCH 24/54] md/raid1: Improve another size determination in  setup_conf() SF Markus Elfring <elfring@users.sourceforge.net> - 2016-10-06 11:30 +0200

#1496485 — [PATCH 24/54] md/raid1: Improve another size determination in setup_conf()

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 4 Oct 2016 21:46:18 +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.
