The community agreement seems to have been that we can get rid of dma_fence_init64(), so let's do that already. In the meantime we can continue our discussions regarding the race in [1]. This also touches the Rust dma_fence, which actually should use 64-bit seqnos (was forgotten so far). Rust fence has no users currently, so needs no backporting, so I would like to address that in a distinct patch. Tested on Nouveau with and without the SEQNO64 flag. Nouveau also uses the USER flag, so I hope we're fine. P.
