From 86a5132ec3989440708d77328891cd63dc3c86ad Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 13 Apr 2012 12:32:09 +0200 Subject: [PATCH] mm: vmalloc: use const void * for caller argument 'const void *' is a safer type for caller function type. This patch updates all references to caller function type.
