From 36b7b6d465489c4754c4fd66fcec6086eba87896 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 10 Jun 2009 23:42:36 +0300 Subject: [PATCH] sched: use kzalloc() instead of the bootmem allocator Now that kmem_cache_init() happens before sched_init(), we should use kzalloc() and not the bootmem allocator.
