[dm-devel] [PATCH 1/9] md/dm-table: Use kmalloc_array() in realloc_argv()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 1 Oct 2016 06:47:16 +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 "kmalloc_array".

This issue was detected by using the Coccinelle software.
