A lot of CPU time is wasted on allocating, populating, and copying debug names back and forth with userspace when they're not actually needed. We can't just remove the name buffers from the various sync data structures though because we must preserve ABI compatibility with userspace, but instead we can just pretend the name fields of the user-shared structs aren't there. This massively reduces the sizes of memory allocated for these data structures and the amount of data passed between userspace, as well as eliminates a kzalloc() entirely from sync_file_ioctl_fence_info(), thus improving graphics performance.
