[PATCH 09/15] md-cluster: Improve another size determination in lockres_init()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 1 Oct 2016 13:02:18 +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 according to the Linux coding style convention.
