sync_file is useful to connect one or more fences to the file. The file is used by userspace to track fences.

Is there a value in keeping the abi unchanged? If not, then Documentation/ioctl/botching-up-ioctls.txt is worth a read.
None from me. I'll look where we can improve the ABI.
Looking at the patch, it seems you kept SYNC_IOC_WAIT, won't it be better to remove it, and only support waiting with polling? The code for polling should already work.
Sure, that makes sense for me.
It's very unclear what format @driver_data has. I kept it for compatibility with android, but it's not clear to me how a userspace consumer would print it. Is there a usecase for this, or could it be removed from fence and sync_file?
I don't have any usecase for this. I'd say we remove it for now and if someone needs this in the future we can talk about this again.
