From 3e12302705a961cfe86d52155b4a8cbb34214748 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 31 Jul 2013 17:00:04 -0700 Subject: drm/i915: BUG_ON put_pages later With multiple VMs, the eviction code benefits from being able to blindly put pages without needing to know if there are any entities still holding on to those pages. As such it's preferable to return the -EBUSY before the BUG. Eviction code is the only user for now, but overall it makes sense anyway, IMO.
