From 100d13c3b5b9410f604b86f5e0a34da64b8cf659 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 9 May 2012 16:55:19 +0100 Subject: kmemleak: Fix the kmemleak tracking of the percpu areas with !SMP Kmemleak tracks the percpu allocations via a specific API and the originally allocated areas must be removed from kmemleak (via kmemleak_free). The code was already doing this for SMP systems.
