Subject: [PATCH 01/11] compat_ioctl: remove keyboard ioctl translation
Date:   Sat,  8 Sep 2018 16:28:07 +0200
Message-Id: <20180908142837.2819693-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The KD* family of ioctls is implemented in two drivers:
drivers/tty/vt and drivers/s390/char/tty3270.c. Both of them
have compat handlers for all their ioctl commands, so translation
in fs/compat_ioctl.c is never used.

Commit fb07a5f857ac ("compat_ioctl: remove all VT ioctl handling")
removed the compat handling for all the other VT ioctls back in
2009, but it seems I missed the keyboard ones back then.
