Hi All,
What's the role or value of the third argument in the
vhost_net_ioctl function in /drivers/vhost/net.c .
The function declaration is
static long vhost_net_ioctl(struct file *f, unsigned int
ioctl, unsigned long arg)
As per my knowledge,
*f represents the fd of vhost-net device,
ioctl any device request like VHOST_NET_SET_BACKEND,
But what's the third arg represent ?
With hope,
Devi.
