Date: Thu, 17 Aug 2017 22:14:39 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Martin Brandenburg <martin@...ibond.com>, Mike Marshall <hubcap@...ibond.com>, kernel-janitors@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH 2/3] orangefs: Use kcalloc() in orangefs_prepare_cdm_array() From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Thu, 17 Aug 2017 21:18:01 +0200 * 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.
