Message-Id: <1272359898-32020-10-git-send-email-jkacur@redhat.com>
Date: Tue, 27 Apr 2010 11:18:17 +0200
From: John Kacur <jkacur@...hat.com>
To: Arnd Bergmann <arnd@...db.de>, lkml <linux-kernel@...r.kernel.org>
Cc: Arnd Bergmann <arnd@...db.de>,
Linus Torvalds <torvalds@...ux-foundation.org>,
Frederic Weisbecker <fweisbec@...il.com>,
Jan Blunck <jblunck@...il.com>,
Thomas Gleixner <tglx@...utronix.de>,
John Kacur <jkacur@...hat.com>
Subject: [PATCH 09/10] drivers: push down BKL into various drivers
From: Arnd Bergmann <arnd@...db.de>
These are the last remaining device drivers using
the ->ioctl file operation in the drivers directory.
Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixed merge conflicts that result from having applied
Linus's Preparation for BKL'ed ioctl removal patch first.
Signed-off-by: John Kacur <jkacur@...hat.com>
