From 5e273a0e06ee5a50bb9cd40026177feca060c101 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 17 Aug 2017 21:18:01 +0200 Subject: orangefs: Use kcalloc() in orangefs_prepare_cdm_array() * A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
