From 2f48e06102b2541c0957a223c923dc8036112142 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 6 May 2017 09:34:53 +0200 Subject: [PATCH] dlm: Use kcalloc() in two functions * Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus reuse the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of data structures by pointer dereferences to make the corresponding size determinations a bit safer according to the Linux coding style convention.
