It's basically a limitation of the on-disk format definition that
has been carried over from Irix. It is an arbitrary limit - the real
limit is the maximum size of an attribute (64KB) and we plan to
raise it to that limit as part of the upcoming on-disk format
changes for metadata checksums...
Cheers,
Dave.

What's the proposed time frame or kernel version for this change?
