If you mount the filesystem with `-t ext4dev -o extents' then create some
extenty files, then unount it and then mount it without `-o extents', the
driver will then refuse to create extenty files.

IOW: you need to give it `-o extents' each time.

That seems fairly pointless.  In fact, if I'd created the fs with `mke2fs
-O extents' (which doesn't work at present) then I'd expect it to use
extents from thereon after, without requiring `mount -o extents'.
