We currently have 32bit block numbers, allowing 4T filesystems. At
min 1 block per inode 4G of inodes should be enough for now.

But you're right. Whenever an overhaul is done, it should plan to
allow for 64 bits of inode info ASAP.

I've run into the "file should be < 2G" problem myself repeatedly by
now, so I consider the probem "more acute" than the large inodes.
