Subject: [PATCH 04/10] dlm: Use kcalloc() in dlm_scan_waiters()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
