Subject: [PATCH 2/4] Add module param type 'ullong'
Date: Wed, 25 Jun 2014 15:27:37 +0200 [thread overview]
Message-ID: <1403702859-74437-3-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1403702859-74437-1-git-send-email-hare@suse.de>
Some driver might want to pass in an 64-bit value, so introduce
a module param type 'ullong'.
