Subject: [PATCH 06/11] compat_ioctl: remove /dev/random commands
Date: Sat,  8 Sep 2018 16:28:12 +0200	[thread overview]
Message-ID: <20180908142837.2819693-6-arnd@arndb.de> (raw)
In-Reply-To: <20180908142837.2819693-1-arnd@arndb.de>

These are all handled by the random driver, so instead of listing
each ioctl, we can just use the same function to deal with both
native and compat commands.
