It looks like new uapi on the technical level, even though from a higher
level it is just an application of existing uapi across more modes, so
why fixes and who is the consumer?

Submitting semaphores from userspace for batches under construction
[passed between processes via syncobj/sync-file]. iris has a bug where
it is trying to wait on a future fence to be submitted and cannot --
but we already have the uapi to handle that elsewhere.

I am all for consistent uapi and this looks simple enough to me.
