I know ext4 even has a much lower limit. But some filesystems don't hav= e a limit, and there the kernel 64k limit strikes in. The EA size limit of = some file systems could also be increased. As there is a real use case for t= hat I guess filesystems would like to be able to support larger EA sizes.
