From 1d2c8eea698514cfaa53fc991b960791d09508e1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 4 Oct 2006 02:15:25 -0700 Subject: [PATCH] slab: clean up leak tracking ifdefs a little bit - rename ____kmalloc to kmalloc_track_caller so that people have a chance to guess what it does just from it's name. Add a comment describing it for those who don't. Also move it after kmalloc in slab.h so people get less confused when they are just looking for kmalloc - move things around in slab.c a little to reduce the ifdef mess.
