+ i915_gem_ww_unlock_single(backup); + i915_gem_object_put(backup);I assume we need to set ttm.backup = NULL somewhere here on the failure path, or don't drop the ref? Or at least it looks like potential uaf later?
Yes, I think on failure, we just don't drop the ref here in case something at some point decides to retry.
I'll fix up this and other comments. /Thomas
