But userspace can't retrieve the unique ID without fsinfo() as things stand.
I'm changing it so that the fields are 64-bit, but initialised with the existing mount ID in the notifications set. The fsinfo set changes that to a unique ID. I'm tempted to make the unique IDs start at UINT_MAX+1 to disambiguate them.
