Tsirkin Date: Fri, 15 May 2020 15:29:53 +0000 (-0400) Subject: vhost: missing __user tags X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1b0be99f1a426d9f17ced95c4118c6641a2ff13d;p=linux.git vhost: missing __user tags sparse warns about converting void * to void __user *. This is not new but only got noticed now that vhost is built on more systems. This is just a question of __user tags missing in a couple of places, so fix it up.
