Right, so that's not something that's going to fly.. we need to support multiple users, including nesting of those. Again, you're adding something to the generic kernel infrastructure, it had better be usable :-) > I guess we could change that once a second user shows up No, we fix that before it all goes in. I would _so_ hate to find out it cannot be 'fixed' and be stuck with a half-arsed sync primitive in the core kernel that's only every usable by the one existent user. So for now, forget all about TTM, DMA-BUF and other such coolness except to verify that whatever we end up with does indeed work for the case you need it for ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
