I would squash this one with patch #6.

Coding style: The lines stating with "!(ctx" and "bo->resv" are to far
to the right.
Additional to that I think ctx is mandatory and doesn't need a check
(but might be wrong). If it isn't it's probably time to make it mandatory.
And I would use (ctx->on_alloc_stage || list_empty(&bo->ddestroy)) as
check, we probably still want to be able to handle deleted BOs here
during CS.
Christian.
