From 5be4c944e83b32c0c6842130df3dc1d46cd6eb1f Mon Sep 17 00:00:00 2001
From: Jens Axboe <axboe@kernel.dk>
Date: Mon, 11 Feb 2013 16:33:25 +0100
Subject: [PATCH] Initialize global and non-static variables

Don't assume they get zeroed. The AIX linker throws a hissy fit on
these, refusing to link the program.
