Almost everyone uses dma_fence_default_wait.
v2: Also remove the BUG_ON(!ops->wait) (Chris).
I just don't get the rationale for implicit over explicit.
Closer approximation of dwim semantics. There's been tons of patch series all over drm and related places to get there, once we have a big pile of implementations and know what the dwim semantics should be. Individually they're all not much, in aggregate they substantially simplify simple drivers.
I also think clearer separation between optional optimization hooks and mandatory core parts is useful in itself.
A new spelling of midlayer ;) I don't see the contradiction with a driver saying use the default and simplicity. (I know which one the compiler thinks is simpler ;) -Chris
