I have two questions:
a) Why not use EUCLEAN everywhere instead?
Having two different names for the same errno complicates grepping.
b) Perhaps both errors should use different values? Do they have the
same semantics? I'm not a fs developer, so this is a bit fuzzy to me.
According to Documentation/, one seems to originate in mtd, the
other in xfs.

when I'm talking to journalists I just say "programmer" or something like that.
