[PATCH] slab: Adds two missing kmalloc() checks.

From: Luiz Fernando Capitulino
Date: Mon Jan 23 2006 - 11:10:54 EST



Adds two missing kmalloc() checks in kmem_cache_init(). The check is worth
because if kmalloc() fails we'll have a nice message instead of a OOPS (which
will make us look for a bug).

We're using BUG_ON() so that embedded people can disable it.
