[PATCH] vhost-net: add module alias
From: Stephen Hemminger <hidden>
Date: 2012-01-11 04:54:00
Also in:
kvm, virtualization
By adding the a module alias, programs (or users) won't have to explicitly call modprobe. Vhost-net will always be available if built into the kernel. It does require assigning a permanent minor number for depmod to work. Choose one next to TUN since this driver is related to it. Also, use C99 style initialization.
