Sure, I can understand that. The bug looks like regular slab
corruption which could have been caused the nvidia blob. So I think
the issue should be closed unless someone can reproduce it without the
blob.

That said, sys_inotify_add_watch() also appears in the trace and
there's been quite a few bug fixes in that area recently so I guess we
should CC Eric Paris just in case the oops rings a bell to him.
