From 52bda2b5bab87c388848bbc0f4d28d04858d5a7d Mon Sep 17 00:00:00 2001 From: David Teigland Date: Wed, 7 Nov 2007 09:06:49 -0600 Subject: dlm: use dlm prefix on alloc and free functions The dlm functions in memory.c should use the dlm_ prefix. Also, use kzalloc/kfree directly for dlm_direntry's, removing the wrapper functions.
