[PATCH] XATTR support on JFFS2 (version. 5)

Hi,

I also agree David's opinion.

In addition, those functions are deployed enough locally-separating
in xattr.c.
Sorry, I could not understand your dissatisfaction.

Is the 'raw' used as the common name for jffs2_raw_node_ref, not 'ref',
isn't it? Because I thought those are not confusable, I adopted 'ref'
as a name of jffs2_xattr_ref.

If we can arrive an agreement that it's confusable naming scheme,
I'll prepare to change the common name of jffs2_xattr_ref.
Both naming schemes are acceptable for me.

It's important to decide what should be decided at first, I think.

Thanks,
