From 1936f8f30066cd608d1cee5807a2adf380dda718 Mon Sep 17 00:00:00 2001 From: Himanshu Jha Date: Sun, 14 Jan 2018 01:56:58 +0530 Subject: Coccinelle: kzalloc-simple: Rename kzalloc-simple to zalloc-simple Rename kzalloc-simple to zalloc-simple since now the rule is not specific to kzalloc function only, but also to many other zero memory allocating functions specified in the rule.
