From c376222960ae91d5ffb9197ee36771aaed1d9f90 Mon Sep 17 00:00:00 2001
From: "Robert P. J. Day" <rpjday@mindspring.com>
Date: Sat, 10 Feb 2007 01:45:03 -0800
Subject: [PATCH] Transform kmem_cache_alloc()+memset(0) ->
 kmem_cache_zalloc().

Replace appropriate pairs of "kmem_cache_alloc()" + "memset(0)" with the
corresponding "kmem_cache_zalloc()" call.
