[PATCH 04/15] md-cluster: Improve another size determination in __sendmsg()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 1 Oct 2016 12:21:48 +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.
