From 5c340eee0020717c793fd9d7e74e5f065225a8f3 Mon Sep 17 00:00:00 2001
From: Miloslav Trmač <mitr@redhat.com>
Date: Tue, 24 Aug 2010 20:17:51 +0200
Subject: Provide file_operations::unlocked_ioctl.

file_operations::ioctl is no longer supported in recent kernels.
compat_ioctl is not running under the BKL, so the code has to do its own
locking anyway (although not everything currently does).
