Debugging fd mix-ups (ie. where, possibly via close()ing the original fd, etc, you end up with something that is a valid fd but not a valid *fence* fd) can be difficult. Fortunately we can use the FILE_INFO ioctl, which will return an error if the fd is not a fence fd. For android, we instead use the libsync API, which does a similar thing on modern kernels, but has a fallback path for older android kernels. Note that the FILE_INFO ioctl has existed upstream since at least prior to destaging of sync_file.
