Subject: [PATCH v5 11/18] tty: handle compat PPP ioctls
Date: Wed, 14 Aug 2019 22:54:46 +0200 [thread overview]
Message-ID: <20190814205521.122180-2-arnd@arndb.de> (raw)
In-Reply-To: <20190814204259.120942-1-arnd@arndb.de>
Multiple tty devices are have tty devices that handle the
PPPIOCGUNIT and PPPIOCGCHAN ioctls. To avoid adding a compat_ioctl
handler to each of those, add it directly in tty_compat_ioctl
so we can remove the calls from fs/compat_ioctl.c.
