Explicitly assign the default priority, and give it a name (macro).

 	kref_init(&ctx->ref);
 	list_add_tail(&ctx->link, &dev_priv->context_list);
 	ctx->i915 = dev_priv;
+	ctx->priority = I915_PRIORITY_DFL;

I915_PRIORITY_DEFAULT would work better.

On the one hand I have the symmetry with MIN, DFL, MAX, on the other
hand DFL is plain bizarre.

DEF?

I915_PRIORITY_DEFEAT. I'm perfectly happy just to 0, pesky Tvrtko.

Will to argue deflated. :) I suggested it for benefit in one of the later patches which explicitly compared against zero. if < 0 && !cap_sys_admin or something.. I thought being explicit what zero means there would be a good thing.

DEFAULT or DEF both sounds good to me. Or NORMAL. DFL is not entirely new (SIG_DFL) but it does look very weird.

Regards,

Tvrtko
