Subject: [PATCH v5 18/29] compat_ioctl: move rfcomm handlers into driver
Date: Tue, 30 Jul 2019 21:55:34 +0200 [thread overview]
Message-ID: <20190730195819.901457-6-arnd@arndb.de> (raw)
In-Reply-To: <20190730195819.901457-1-arnd@arndb.de>
All these ioctl commands are compatible, so we can handle
them with a trivial wrapper in rfcomm/sock.c and remove
the listing in fs/compat_ioctl.c.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
