Re: [PATCH] drm: stop vmgfx driver explosion

----- Original Message -----

If you do a page flip with no flags set then event is NULL. If event is NULL then the vmw_gfx driver likes to go digging into NULL and extracts NULL->base.file_priv.

On a modern kernel with NULL mapping protection it's just another oops, without it there are some "intriguing" possibilities.

What it should do is an open question but that for the driver owners to sort out.

I think CC stable is in order.
