	We've not agreed yet on how we want to implement them.  We go
back and forth.  Could be internal to the inode reserved space for a few
small xattrs, expanding to a whole cluster for larger ones.  Or it could
be block-based, copying the code directly from ext3.  We just haven't
decided yet.
	Note that there is no extra room at the "end" of the inode, as
the extent list fills to the end.  The extra room is in the reserved
fields.
